No-BS Book Reviews: "Work. Pump. Repeat" by Jessica Shortall

There are a lot of breastfeeding books out there, and quite a few that I wouldn't recommend to anyone who has to work outside the home in their baby's first year. So it's refreshing to come across a nursing-while-working book which I feel I could actually give to a new mother without worrying that I am going to send her off into a tailspin of anxiety and depression. The book is "Work. Pump. Repeat" by Jessica Shortall, and I got an advance preview of it shortly before its recent release.

The most striking thing about the book is its briskly efficient use of floor-space. As the author tells us, she is not going to tell us about the football hold or lactation cookies, because there are about 2,500 breastfeeding books that do that already. Nor does she waste time on giving us reasons to breastfeed--if we've bought the book, we've probably made our decision by now. 

As a result, almost the entire book is freed up for the most fantastically detailed, practical advice--real stuff, hands-on, mum-tested. The sort of stuff you hear on your favorite forums and Facebook groups, yet somehow never get round to actually copying and pasting into a single place so that you will have all the tips when you need them; it's all here, digested, sorted and put into readable form. Are you looking for advice on how to speed things up if your company has assigned a pumping room in another building? It's here. Practical hints on the best type of clothing to disguise milk leaks? Look no further. What to do if you have no alternative other than to pump in a toilet cubicle? Sorry you had to look for it, but there's detailed advice about that too (did you know that keeping some Post-it notes in your handbag can come in handy for this situation? If you are wondering why, read the book). 

Pump choice, pump usage, bottles, freezers and getting your baby ready for taking breastmilk at daycare are discussed, followed by discussion on practical clothing choices, your rights at work, and how to handle your boss and coworkers. All sections are full of concrete, non-judgmental advice that has a "been there, done that" feel to it. The workplace section is really, really pragmatic. Shortall's research for the book included talking to large numbers of HR /management people, trying to work out what are the best tactics for the average Jane who does want to pump at work but cannot afford to antagonize her boss and lose her job/damage her career prospects with a "These are my rights!" attitude. And the book also gives practical tips on "guerrilla pumping"--how to get by at work as best you can if no proper accommodation is made for your needs. The book puts a lot of emphasis on the everyday realities of breastfeeding, with the workplace plan-of-action broken down in detail to include things like how and how often to wash pump parts, dealing with special and unusual pumping situations, flying with breastmilk, and how to approach HR to suggest improvements for pumping facilities. 

Things I would have liked to have seen? I would have preferred slightly more specific info on the freezer storage times/nutritional value question, including differentiation between chest freezers versus regular freezers. I also think that the discussion on lipase/funky-tasting frozen milk would have been better placed closer to the beginning rather than in the troubleshooting section at the end; given the number of women who end up wasting hours and hours producing freezers full of undrinkable milk, every woman who is going to store serious amounts of the stuff should consider testing for lipase before she gets going. One final point is that I would have attached a brief health warning before advising mothers to read books like The Womanly Art of Breastfeeding and The Nursing Mother's Companion. Not that they aren't potentially useful resources too, but a working mother would be well advised to take some of their advice and philosophies with a pinch of salt, especially since some of it (like advising mothers to leave bottle introduction really late) could potentially sabotage one's ability to return to work and stay sane. Lactation consultants as a group perhaps need a health warning as well, for similar reasons.

Sometimes the book made me feel sad. Because when you're reading a section which gives hints about how to get your pump parts clean at work without anyone seeing them, or how to multitask while pumping to deflect criticism from coworkers about your constant "breaks," part of you thinks "Oh, that's a clever idea," and the other part of you thinks "This is so depressing. Because you have all these women working full time with tiny babies, driving themselves nuts trying to pump and store their babies food all day long, waking up all night long, and then having to hide their pump parts from coworkers because God forbid anyone should suffer the disgusting situation of glimpsing a clean breast pump." And it's just all so sad. But given that this is the crappy reality that US mothers face, I am glad that at least writers like Shortall are doing their bit to try and make things a bit easier for mums.

The other thing that makes the book a standout (other than the level of detail) is the emotional care that the author shows towards her fellow WOH breastfeeders. When she says that "this is a judgment-free zone" she really is not kidding. It is rare and refreshing to see a breastfeeding book that talks about formula choice, preparation and supplementation simply as another option, rather than as some kind of existential failure on a mother's behalf. Shortall also describes her own personal journey from exclusive-breastfeeding obsession to a more pragmatic approach with her second child, and it's clear that is part of the reason why she urges mothers to safeguard their mental health--advice that is not confined to an occasional vague disclaimer about "not judging people," but rather is something that is built into the very structure of the book, influencing all the advice it gives.

In short? Without a doubt, the best and most practical book for WOH nursing mothers that I've encountered, and an excellent buy or gift.

Here is an excerpt from Chapter 3 of the book. Enjoy.

Pumping School

Welcome to School

Pumping makes many women feel like farm animals. For me, it is everything actual nursing is not: sanitized, cold (sometimes literally, if you’ve just washed the parts or tend to keep them in the fridge at work in between sessions), and industrial. It was also totally and completely foreign to me, up until the first time I tried doing it, which is where Pumping School comes in.

Unless they make you pump in the hospital (which can happen), you might find yourself at home, with a baby and a very porn-star-esque pair of boobs, wondering who the hell is going to show you how to use this thing.

I needed someone who could see me with my shirt off to show me how to do it. So my best friend took me to Pumping School.

How to Get Taught

Between weeks three and six of your baby’s life, invite to your home a mother with recent experience with pumping breastmilk. This should be a woman with whom you are comfortable seeing both of your newly gigantic boobs. 

Tell her that she is coming over to teach you how to use a breast pump. You should have your pump and its basic parts, breastmilk storage bags, and a Sharpie or other permanent marker. Time this date so your friend comes by just before the first morning feeding (or during, if she has a key or you have someone else to open the front door for her while you have a baby attached to you). If she has a toddler, suggest that she leave this lovely small person at home. 

You’re going to feed your baby as normal, then pump immediately after the feeding. I recognize how silly and arbitrary a term like “first morning feeding” is. Just pretend that any feeding at or after 6:00 A.M. is the first one of the day, even if it isn’t and it makes you want to throw this book against the wall.

The reason you’d shoot for the first morning feeding for pumping is that your body is making more milk at this time of day. Also, it can help trick your body into making a bit more milk throughout the day. If for some reason you just can’t do this time of day, it is not the end of the world. 

Once you’ve nursed, your friend will set you up with the pump—placing the parts onto your boobs if need be—and have you pump for the first time. She will show you how most pumps have an initial “letdown” setting, which pumps quickly and with less suction, to simulate the way your baby sucks when she is first on your breast. Your friend will show you how it then switches over to the general setting, resulting in slower and deeper suction cycles, again to simulate what your baby does once the milk starts flowing. 

Break for Questions 

Here’s what you might worry about in this process:
1. If I pump after I feed the baby, will I have enough milk for the next feeding? Yes, you’ll be fine. Your breasts are always making milk and you don’t need to “fill up.” In fact, you will probably produce more milk that day because of the increased demand.
2. Will there be any milk to pump since my baby just finished eating? Maybe. Maybe not. This first time around is just for practice, so don’t sweat it if all you see is a few drops.
3. Am I really going to do this several times a day when I go back to work? Um, yes. That’s why you bought this book, honey. If you want to breastfeed after you’re back at work, you are probably going to pump a lot at work. It’s not fun, but it is doable. 
4. Who is going to hold the baby while I do Pumping School? Options: your Pumping School teacher, your spouse, a baby swing or chair, or the floor.

Back to School

During the first fifteen minutes or so (which aren’t going to feel awesome), you might produce a couple of drops, or you might produce 4 ounces and feel awesome. There is no definition of success, other than learning how to do it so it stops seeming so foreign and weird. (Note: It will never completely stop seeming foreign and weird.)

You are going to see, for example, that your nipples are stretching to a greater length than you thought possible (a friend described seeing his wife pumping for the first time as “two thumbs in a garden hose”). 

You are going to wonder what will happen to your sex life if/when (it’s a “when,” trust me) your partner sees this process. It will be awkward, but you’ll both survive it.

You might be surprised to see what your breastmilk looks like. It can be thin and watery or thick and creamy. It can be white, yellowish, bluish, or greenish. In fact, it will be all of the above (which is normal) at different times of the day and over time.

Congratulations. You’ve just joined the most exhausted, most multitasking, most ass-kicking club of women in the world.

Fat vaginas and shrinking newborns in Japan

When I got pregnant I weighed 53 kilos at 170cm (118 pounds, 5’8); I gained 13 kilos or 28 pounds over my pregnancy. My daughter was born at just 2.6 kilos (5 pounds 11 ounces). By British or US criteria my gain was fine, and indeed I found myself wondering if I should have gained a bit more, judging by my baby’s rather modest size. Yet by Japanese standards I had gained an excessive amount. Welcome to the insane world of the incredible shrinking Japanese pregnancy.

Official guidelines in Japan recommend that women gain 7-12 kilos if they are normal weight, and 9-12 kilos if they are underweight—significantly lower than the guidelines of the UK and US. However, these figures mask the reality that is going on in clinics and hospitals where doctors routinely pressure women to gain even less than the official limits. “My doctor told me I should stop eating all fruit and carbohydrates,” complains one mum (whose weight gain was picture perfect according to the US guidelines). “I was scolded by the nurses every time I went in; they said I wouldn’t be able to push the baby out,” says another. Others reveal stories of doctors telling them they should be losing rather than gaining weight during pregnancy, or informing them that they would get a “fat vagina” unless they drastically restricted their calorie intake. No, I don’t know what a fat vagina looks like either.

What are the trends in newborn weight?
Perhaps part of the anxiety about gaining too much weight comes from the widespread misconception in Japan that average the average newborn is getting heavier. In fact, birthweights did rise through the 1960s and 1970s in Japan, but from about 1980 the trend went into reverse, with birth weights falling by 125g in the past 25 years. It seems that previous decades' anxieties about “babies getting too big” may have lingered on into the present, distorting doctors’ and the public’s perceptions.

To a certain extent it is understandable that Japanese medical authorities became worried by fact that babies and mothers were growing a bit heavier during the 1960s and 1970s. If a woman genuinely does gain too much during pregnancy, it does indeed increase the risk of difficult births, and this may be particularly true for Asian women. Asian women who gain too much are significantly more likely to develop gestational diabetes than other ethnicities. Big babies may be more likely to wreak havoc on an Asian mother’s body, as there is also some evidence that women of Asian ethnicity are more likely to sustain serious perineal tears in childbirth. Nobody is quite sure why—perhaps it is because Asian babies are proportionally larger compared to their relatively small mothers. In most developed/middle income Asian countries, this problem is increasingly being circumvented through very high cesarean rates (40-50% in countries like China and Vietnam). But the Japanese remain emotionally and culturally committed to the idea of natural childbirth; not surprisingly, a “Keep ’em small at all costs” mentality has tended to develop. 

I suppose there is a sort of “sunk-cost fallacy” in such matters—if you have spent the last decade or two telling women to severely restrict their weight, the possibility that this advice may have been harming babies may be too painful to confront. Easier to keep telling yourself that your advice is correct and always has been. It’s not like Japanese healthcare providers are exactly great at accepting questioning at the best of time.

Oh, and it’s very, very hard to get an epidural in Japan, due to a critical shortage of anesthesiologists and the cultural belief that mothers are “supposed” to suffer in childbirth, and this has probably also encouraged doctors and midwives (all of whom will have watched women suffering in long, hard labors) to encourage mothers to keep their bellies and babies small. In fact, a small baby does not always equal an easy birth--I know women who’ve torn badly pushing out five-pounders--but when you are staring down the barrel of a completely unmedicated labor with absolutely no way out of it, you are naturally going to clutch at whatever straws are available to you which might, maybe, just make things a bit easier. Add in standards of beauty which demand insect-like thinness in women even before pregnancy, and you have a perfect storm for extreme weight restriction in pregnant women. 

The consequences
Slowly, however, awareness is growing in Japan about the risks of too little weight gain in pregnancy. Japanese midwives are still heard to express enthusiasm about the idea of keeping fetuses small and then feeding them up after delivery, but as the doctor quoted in the Bloomberg article puts it, “Being born small and growing big is the worst possible scenario for risk of disease." Babies undernourished in the womb and born small may be at elevated risk of problems such as obesity and hypertension later in life,  possibly because such undernourishment sends out signals that cause the fetus's body to prepare for famine conditions in the outside world (an extreme form of this was seen in the babies born after the Dutch Hunger Winter of 1944-45, who have proven to be more prone to problems such as cardiovascular disease as adults).  

A need for balance
It’s not that we need a complete free-for-all either. Most women I know who gave birth in the UK report that they were never weighed or given any advice on weight gain, a fact which is almost certainly connected with the fact that the percentage of deliveries assisted by forceps has doubled over the last 10 years as mothers start their pregnancies heavier, gain more and have bigger babies. It’s completely reasonable for healthcare providers to be honest with patients about the fact that excessive weight gain increases the risk of difficult births, not to mention the fact that (in my own experience) women who gain huge amounts are more likely to feel uncomfortable during pregnancy and have an difficult psychological transition to motherhood afterwards. 

Nevertheless, there is mounting evidence that excessively strict weight guidelines in Japan are putting the health of babies at risk, and making pregnancy--which is supposed to be one of the happiest times in a mother's life--into a period of unnecessary anxiety, guilt and embarrassment for women. While a certain amount of caution regarding weight gain is probably advisable for Japanese women in particular, given ethnic factors relating to gestational diabetes and the problem of perineal trauma, the advice to restrict weight in pregnancy seems to have become unnecessarily extreme and to have taken on a life of its own. For mothers' and babies' sake, it's time for Japanese healthcare providers to swallow their pride and review their policies on gestational weight gain.

Is there a need for more nuance in the vaccine "debate"?

Alice Dreger--an academic whose gutsiness in taking up controversial issues I have a lot of respect for--has recently written an article on yet another hot-button topic: A heretic in
the academy: What if not all parents who question vaccines are foolish and anti-science? on the book Vaccine, by Mark Largent.

Prof. Largent is basically in favor of vaccination and wants to increase coverage; however, he also criticizes some of the doctors, journalists and bloggers who have pushed the pro-vaccine line. Largent suggests that some of these people have made things more difficult by adopting all-or-nothing arguments about vaccination, as though refusing the chickenpox vaccine were the same as refusing the polio vax. He points out (correctly) that the US vaccination schedule is not based exclusively on medical evidence but is also influenced by commercial interests. He suggests a distinction between hard-core anti-vaccinators versus parents who are merely a bit anxious or who reject one or two vaccines, stating we might have more luck if we showed empathy with their worries. Dreger, describing Largent's ideas, also adds some personal stories about the gut-level fear she felt about the number of needles coming towards her child, in spite of her own strong conviction that vaccination is safe and necessary.

By using terms like "zealots" to describe some of the pro-vax people, Largent and Dreger aren't certainly out to win any friends, and both have already attracted some fierce criticism among science-based-medicine blogs on the grounds that they are going soft/pandering to parents who believe stupid things about vaccines. I do know what they mean, sort of. I personally was never one of those parents who felt gut-level "anxiety" about needles being stuck in my child, so Dreger's description of her own fears didn't resonate with me at all. The number of vaccines which are given to children in the United States certainly does sound like a lot at first glance... then again, I live in Japan with its relatively "light" vaccine schedule (Japan tends to be incredibly conservative about new vaccines and tends to panic and ban any shot that is even rumored to have created an adverse reaction); this has not been a roaring success. Japan has long been known as an "exporter" of measles due to frequent outbreaks--and as someone with no hearing in one ear due to mumps I was horrified to learn that the mumps vax is still not standard here, and that mumps regularly makes the rounds in Japanese universities.

And yet
That said, when the writer uses the phrase "vaccine zealot," honestly, I do know what she is talking about. Examples:

1) A mother posts online asking for advice about the chickenpox which her child has contracted. When it transpires that the mother had not vaccinated her child against this virus, a horde of posters descend on her and subject her to a lot of incredibly harsh, personal criticism faintly tinged with hysteria. After a while, another poster points out that there is a bit of controversy over the population-level effects of the chickenpox vaccine, which is why the British National Health Service (NHS) does not routinely offer it. The pro CP-vaccine posters, instead of admitting that the issue is somewhat nuanced, merely buzz even more angrily, all but accusing the original poster of wanting to murder immune-compromised children. 
2) A mum on a Facebook group announces that there have been a few cases of whooping cough in her state--the other side of her state from where she is living--and that she intends to avoid all unnecessary movement outside her home and stay indoors with her baby (not immune-compromised) for the immediate future. She receives responses of the "We are all praying for you!" type, as though the kid were already on its deathbed.
3) In an argument about the measles, mumps and rubella (MMR) vaccine, a poster correctly states that measles can potentially kill and cause serious complications--but cites statistics taken from developing countries, suggesting that a measles epidemic in the United States would kill up to 10% of those infected. The other posters on the discussion mostly know that this is bullshit but don't dare point this out, because this would risk giving ammunition to all the anti-vax posters who are on the same thread. (This article goes one further, claiming that more than half (!) of those infected with measles last year died of it, which if true would make measles deadlier than smallpox...!)

Okay, 1): Although the chickenpox vax is safe and effective, there's genuine concern that widespread vaccination of children against CP could be a factor behind recent increases in painful shingles among the elderly/immune-compromised in some countries (see here). Whether these things are really connected is very debatable; I personally decided to do the CP vax after weighing up the pros and cons. But "weighing up" is the key phrase here: I mean, I wouldn't spit venom at anyone who decided not to. If I had been some vaccine-hesitant parent reading through that thread, the overwhelming impression that I would have come away with would have been: "Vaccine-promoters are kinda selective with the truth and may cover up things which might call their case into question. Oh, and they also appear to be excitable and a little nuts."

Regarding 2): It's sensible and wise for parents to keep an eye on disease outbreaks in one's locality. On the other hand: if some lady announced that she was going to barricade herself in her home due to fear of child-abduction-by-strangers, I suspect that most of us would tell her ever-so-gently to "get a grip," and the risk of whooping cough multiplied by the disease's mortality rate has got to be similar. Worry about very small risks has to be balanced against the benefits of fresh air and having children spend time with friends and family.

3): Measles kills and blinds on an alarming scale in kids with Vitamin A deficiency and a heavy disease burden (chronic parasite infestations etc.). In developed countries, measles kills at a rate of perhaps 1 per several thousand cases. I know most pro-vax blogger etc. absolutely hate the "Brady Bunch" comparison, but honestly, there is some truth to the fact that by the 1960s and 1970s serious complications were rare enough that parents often didn't take measles all that seriously (hence it took quite a long time for the measles vax to catch on).

The reason why we should inoculate against measles is not because an outbreak would cause overflowing graveyards--it wouldn't. It's because nowadays we have very high standards for children's safety, so even a 1 in several thousand risk is worth eliminating, especially considering how incredibly safe this vax is. We wouldn't copy 1960s parents when it comes to car seat usage, either. And 1960s parents didn't know that measles may be connected to later illnesses in children due to "wiping clean" the body's immunity record (see below). Then you've got the issue of immune-compromised kids. There is no need for exaggerated figures when it comes to measles--the factual reality of the disease is already quietly worrying enough.

To be an activist, first be a "factivist"
As someone with a disability caused by a VPD, I feel a certain sense of urgency about the need to increase vaccination rates. If we want to do this, we need to make sure we're actually changing people's minds, not just grandstanding.

I don't know exactly what Largent says, as I haven't read his book. If he is descending into the nonsense of "let's present both sides of the argument" then he's talking out of his backside, because there is basically only one sensible argument here. But if he's talking about the need for sticking to the facts and maintaining a courteous tone in debate, then 
I'm with him.

As Andrew Maynard of the above linked blog post says "
[T]o use data that not only feel wrong, but are not backed up with evidence, only serves to undermines trust in public health experts. Anti-vaccine proponents are smart enough to realize this. Each time the data on infectious diseases and risk are spun beyond their legitimate bounds, anti-vaccine proponents are given a helping hand in winning the hearts and minds of concerned parents." When pro-vax people start to overreach--even by a little--it undermines the credibility of everything we say ever after.

"Courtesy" is important too--not frosty politeness through gritted teeth, but genuinely empathizing with people's worries. And for the love of God, please stop the aggressive dogpiling of people on discussion threads (I'm sure I've been guilty of participating in these in the past, too). Most people who hesitate about vaccination are not hardened anti-vax types, but worried parents who don't know who to trust. If we can talk to them as if we genuinely care about them and their kids, we might be surprised at how willing they are to listen.

What to expect when you wean your child at the age of 4.2 years

When I had my baby, I didn't quite expect that I'd be breastfeeding her for longer than 12 months. If you'd suggested to me that the duration of our nursing "relationship" might be reckoned in years rather than months, I'd have laughed and told you to stop talking nonsense.

And yet it wasn't until a few months ago that I nursed my child for the last time. She was just past her 4th birthday--actually, not so far from the famous "4.2 years" which is sometimes bandied about as the global average for the duration of breastfeeding (not true, as I pointed out in another post). Well, it may not be the global average, but it was the average for my children--or child, rather, since I have just the one child and there probably won't be any more of them.

I carried on nursing for this long mostly because I was simply taking the path of least resistance--I didn't mind nursing her and had no particular reason to stop. I stopped nursing her for pretty much the  same reason. She had been losing interest for the last year or so, and I have other ways to relate to my child. She's old enough to do fun things with, now--we can chuck a ball around, we draw together and sound out simple words, she is developing a keen interest in baking and crafts, especially trying to "make" dresses for her dolls out of tissues and play-dough. I can see she will be into knitting and needlework in a few years' time.

After I had realized that she had basically stopped nursing, I was happy enough but felt slightly bothered, somehow, that I couldn't remember when the "last time" was. So when (a couple of weeks later, shortly after her 4th birthday) she asked to nurse again, I agreed and let her, simply because I wanted that sense of closure. I said to her "This is the last time, though, because you're a big girl now." She said "Yes, Mummy," very calmly and demurely. And we nursed that one last time. And that was it.

That was now several weeks ago. No weird hormonal changes or breast oddities so far. In fact, not-nursing-a-preschooler is pretty much exactly the same as nursing-a-preschooler (it had been so sporadic for that last year, after all). I haven't even stopped producing milk. I can still squeeze a drop or two out, even now--a couple of months later. Sometimes I wonder if that will ever go away.

And I'm still interested in infant feeding politics, and I can't see that changing any time in the future either. That interest has to compete with other sources of interest these days, of course--education-related stuff is the new obsession, and my interest in politics has picked up a lot as well in the past year. But I'll still be keeping the blog going, and in fact I'm aiming to get my act together and start posting a bit more regularly. Some time in the next couple of weeks or so, I will be putting a post together on "the real advantage of nursing a child past 12 months." Watch this space.

Pumping cultures, nursing cultures: Japan, Britain and the United States

I am a British blogger, who lives in Japan... and I follow a lot of motherhood-related stuff in the States, because a lot of my favorite blogs and parenting groups/forums are US-based. There are lots of differences in breastfeeding culture between the three countries that one could potentially talk about--differences in attitudes to supplementation, newborn procedures, cultural oddities like beliefs about alcohol and diet while nursing--but one aspect where one sees big differences is attitudes towards pumping and bottlefeeding expressed milk.

Breastfeeding advocacy has always had an ambiguous, push-me-push-me attitude towards expressing--is it a "good" thing that replaces formula in bottles, or is it a "bad" thing that competes with the act of nursing directly at the breast? You might imagine that cultures which make it easy to nurse your baby directly will also be places that make it easy to pump and bottlefeed your breastmilk. In fact, that's often not the case, as we shall see. A quick disclaimer--the following discussion is mostly based on my personal experiences of these breastfeeding cultures both online and in real life, so this time I don't have a lot of data to back me up. If anyone does have any data that disproves anything here, speak up!

United States
My "main" mums' board when Baby Seal was tiny was predominantly American, and one thing that stood out was the amount of time spent talking about pumping. The United States is almost unique among developed countries in that maternity leave is still not considered standard; unless you are exiting the workforce for a bit, you will probably be back at work about six to eight weeks after giving birth. For US breastfeeders, therefore, pumping is a continual source of conversation, commiseration, competition and anxiety, and US-centric breastfeeding blogs and pages tend to spend a lot of time talking about women's pumping rights at work.

To a certain extent, the normalization of pumping and bottle-feeding EBM has bled over into the experiences of stay-at-home mothers in the US, who often sock away quite substantial amounts of milk in the freezer "just in case," or with the hope of donating it at some point. The custom of carrying bottles of expressed milk around in public for feeding the baby with also seems to be commoner in the US than elsewhere, probably because public breastfeeders are more likely to get hassled (although, like everything else American, this is very regional). Exclusive pumping seems to be commoner in America too--on British fora like Mumsnet, women who want to feed their babies this way are often advised to look on American fora and Facebook pages for advice. Perhaps widespread car ownership also tends to make exclusive pumping a bit more doable in the US than elsewhere, because you can pump in the car and because a car makes it easier to tote bottles, ice packs and heavy-duty breast pumps around with you. A few women even opt for exclusive pumping due to personal choice.

Complete contrast here. Although you won't actually see many women nursing publicly in Japan, Japanese culture seems to be far more accepting of the "nursing relationship" than the States. But while Japanese culture is fairly nursing-friendly, this does not extend to pumping. You can get breastpumps in Japan, of course, and increasing numbers of women use them. But relatively few women work outside the home when their babies are small, due to maternity leave and the fact that so many women leave the workforce for many years or permanently once they have children. Using babysitters also seems to be relatively uncommon.

As a result, the culture of pumping and bottle-feeding EBM has not become rooted in Japanese culture in the way it has in the States. Quite a lot of women do give the odd bottle, but more often than not there will be formula in the bottle--a fact facilitated by the fact that Japanese mothers seem less likely to place a strong premium on breastfeeding exclusively. It's the same story with the pumping side. If you are one of the minority of women who goes back to work early, don't expect much provision or understanding for your pumping needs if you want to pump. I mostly work from home, but was asked to take on an on-site once-a-week position when my daughter was six months old. When I nervously broached the subject of pumping, they were nice enough but said that there was nowhere in the company where I could express milk. Given that the company in question consisted of a 37-storey megablock, I found that hard to believe--but it was clear that my prospective employers were having difficulty envisaging what I was asking for, because they had never received such a request. In the end, I turned down that particular job for unrelated reasons, but it was an awkward moment.

And then there's the question of getting milk into the baby. Like many things in Japan, the process of sending EBM to daycare is based on lots of silly rules and the most unbelievable inefficiency. In theory, public daycares are supposed to accept EBM; in practice, many of them outright refuse, or put enormous pressure on parents to send formula. If they do accept EBM, the majority insist on the milk being frozen first. Some daycares further stipulate that the milk has to be frozen BUT also pumped within the last week (which means that you basically have to pump, freeze the milk, and then almost immediately dig it out of the freezer to thaw it in the fridge). Apparently, even NICUs often insist on using frozen EBM rather than fresh. I have no idea why the Japanese are so obsessed with freezing EBM--are they under the impression that the freezing process "kills germs" or something? It doesn't, of course (and thawed frozen breastmilk is actually more prone to spoilage than milk that's never been frozen, because the freezing process zaps some of the natural microbicidal compounds). Given the critical shortage of daycare spots in big cities in Japan, it's unlikely that we'll see women demanding that daycares change these ridiculous rules any time soon--most women who have got a spot are too busy feeling relieved and grateful to raise many complaints, and content themselves with writing fake dates on their bags of frozen milk.

In Britain, as in America, it would be pretty much unthinkable for a daycare to refuse to handle expressed breastmilk. On the other hand, British women, like their Japanese counterparts, tend not to work full time when their babies are young because most take maternity leave. So pumping has never made quite the inroads into British culture that it has in the States (which is perhaps why the slightly awkward word "express" seems to be the commoner verb to use), although the majority of breastfeeders do own a pump and use it now and again. On British (and Australian) discussion fora, quite a lot of breastfeeding advocates encourage women not to make any use of pumping and bottlefeeding at all, on the grounds that conveying milk this way is unnecessary, might mess up the mother's supply and/or create a preference for artificial teats in the baby, and is less healthy/optimal than direct breastfeeding. I think it would be a rare American lactivist who was so negative about pumping and bottlefeeding; so many American breastfeeders work full-time that she would risk alienating a large percentage of her target audience, and if you overemphasize the difficulties of maintaining breastfeeding through pumping and bottlefeeding to mothers who are going to WOH anyway, they might just give up and decide to use formula instead.

Pumping breastmilk to avoid breastfeeding in public is also far less common in the UK than in the US, because although breastfeeding rates in the UK are low, breastfeeding in public seems to be more acceptable than in the States. In any case, the reality is that when you are with your baby and breastfeeding him or her round the clock, it is really difficult to fit "pumping a bottle and feeding it to the baby" into the routine, and if a baby does not get a bottle regularly--several times a week, at minimum--there is a high chance that he or she will eventually reject bottles altogether (as I discovered to my cost). Consequently, it seems that a large percentage of breastfed babies in the UK will not drink from bottles, and this seems to have contributed towards a general feeling on British parenting boards that breastfed babies "can't be left" for any length of time.

Living in Japan, it's certainly easy for me to be irritated by aspects of the culture which are interconnected with the difficulties of expressing and bottling breastmilk. Japanese culture tends to emphasize the importance of the mother-child bond; this can be liberating in some ways (very few people here will look down on you for breastfeeding a toddler or even letting them share your bed), but it's also connected with the fact that Japan has been very slow to get women into the workplace--something which is now a big problem for Japan given its shrinking workforce and its resistance to accepting large-scale immigration. The cultural squeamishness towards breastmilk that's been separated from the mother's body and the lack of legal protection for pumping at work means that many women are not able to pump their milk or feed it to their babies if they want, which deprives them of choice; others (as outlined above) are forced to go through unnecessary and time-consuming procedures which add to their burden. While maternity leave provision is a good thing, I think we should also recognize the fact that some women want to return to work while their babies are small--and they have every right to do so and leave pumped milk if they wish. I don't think that the cultural resistance towards using babysitters does Japanese marriages any good, and I'm not a fan of seeing cranky babies being toted around to smoky restaurants late at night, as is frequently seen here in Tokyo.

On the other hand, normalization of pumping can also become a trap in its own way. There is a danger that each technological innovation can become something that merely shifts the goalposts of what mothers are expected to be able to achieve. Since breastpumps have been invented, women have increasingly been expected to combine breastfeeding and working outside the home (whereas their mother's generation, if they worked outside the home when their babies were small, just shrugged their shoulders and used formula); more efficient breastpumps have raised the bar higher, with working women increasingly expected not only to "breastfeed" but to "breastfeed exclusively without formula supplementation"; with bigger freezers, better designed storage containers and more affordable double-electric pumps, even women who are not working outside the home may increasingly feel that it is expected and normal to pump "just-in-case" stashes or donate milk. And writers like Olivia Campbell may have a point when they suggest that this technological fix (ever higher-performing breastpumps) has enabled American society to avoid confronting the issue of maternity leave, opting instead to place a double burden (working and pumping) on the shoulders of fragile postpartum mothers. Similarly, because most people in the US are aware that pumping and bottle-feeding EBM is a "thing," this can lead to more pressure on mothers to carry bottles of pumped milk around with them, and can become an excuse for negativity towards women who are trying to nurse their babies in public ("Come on, lady--they invented breastpumps for a reason!! Why don't you just pump a bottle before you leave the house??").

Considering each of the above countries in turn, I think my own country--the UK--probably represents the best overall balance for respecting women's right both to feed at the breast and to pump when they need or want to--although I do wish that there was a bit more awareness in the UK of the fact that bottles are not the only way to get breastmilk into a bottle-refusing baby. I hope that each of these countries can work towards achieving a cultural consensus that will allow women and babies to take advantage of the best aspects of both direct nursing and pumping/bottlefeeding--without either becoming something that places unnecessary burdens on women or restricts their freedom.

Bullshitometer: Women with HIV should not breastfeed their babies

Should HIV-positive mothers breastfeed their babies? Canvas a few different sources--the La Leche League (LLL), the American Association of Pediatrics (AAP) and your local mums' group--and you are apt to get several different replies. Who is right? Read on....

Full circle
The commonly-held feeling that "HIV-positive = Don't breastfeed" dates back to 1985, when the first case came to light of a baby infected with HIV from its mother's milk. In the years following, international agencies and non-governmental organizations (NGOs) around the world rolled out programs for preventing mother-to-child transmission which including advising HIV-positive women not to breastfeed while providing them with free formula milk. Given the extreme panic over what was virtually a death sentence, it seemed like mere common sense at the time.

As the years went on, however, concerns began to be heard about the effects of these policies, especially from NGOs and community leaders on the ground who were beginning to see what the rough end of formula feeding in the developing world actually looked like in practice. Reports began to come in of high mortality and morbidity rates among babies who were being bottle-fed in areas lacking clean water, refrigerators or facilities for sanitizing bottles and teats, and where erratic supplies of formula were resulting in mothers filling in the gaps with cow's milk or by over-diluting bottles.

This is what formula feeding in resource-poor environments looks like. 

Breastfeeding, as it happens, doesn't seem to be a very efficient vector of HIV--not least because it contains certain substances which reduce the risk of transmission; indeed, HIV-positive women produce certain immunoglobulins not found in the milk of HIV-negative women such as anti-HIV-IgG, -IgA and -IgM. As the data began to come in, it became clear that even in the worst-case scenarios (mothers who were taking no medications and who were mixing breastfeeding with formula and other foods), the majority of babies were still free of HIV by the time they weaned. In fact, the rate of babies who both survived and were free from HIV long-term tended to be higher for breastfed babies, because so many formula fed babies were dying of other things (1).

What's more, it was also becoming excitingly apparent that the rate of transmission could be beaten down still further by putting mothers on medications to control their viral loads (2); moreover, sticking exclusively to breastfeeding (rather than adding in formula/solids) for the full six months lowered the risk further still (3). It's not clear why mixed feeding increases risk: perhaps the other substances compromise the integrity of the intestinal mucosa, or perhaps the problem is that in developing countries, food is often premasticated (4) (resulting in tiny amounts of blood from gums mixing with the saliva and chewed food). This could also explain why a small percentage of exclusively formula fed infants also tend to wind up with HIV.

So, to bring the discussion full circle: what are the recommendations for HIV-positive women? Roughly speaking: Women in the developing world are now recommended to breastfeed exclusively for six months, and alongside solid foods until around 12 months old if possible. However, HIV-positive women in developed countries are still advised to choose formula--by the AAP (5), by BHIVA (6) and just about every medical body. Why the difference? Because in rich countries, formula feeding is basically safe/fine, and the risk of infection (while against the odds) is therefore more worrying in comparative terms. Oh, and another point which is often forgotten is that HAART medications themselves tend to get into your breastmilk; studies have indicated fairly low toxicity but also to an increased rate of anemia in infants breastfed by mothers on HAART (5). I wouldn't want my baby drinking HAART-laced milk; these are not very nice drugs at all.

Breastfeeding advocates deserve much applause for their tenaciousness in helping to bring to light the serious drawbacks of bottle-feeding in developing countries, a move that will probably save hundreds of thousands of lives. You would think that that would be enough; however, judging from the HIV-and-breastfeeding information displayed by sources such as Kellymom, LLL and Best For Babes, it appears that some lactivists cannot be content with showing the breastfeeding is the best option for HIV-positive mums in developing countries; rather, they insist on trying to make out that it is the best option for HIV-positive mums in developed countries as well. That, roughly speaking, is where the science ends and the woo starts.

Hard cases
In the UK, a large and growing proportion of HIV-positive mums consists of immigrants/asylum seekers from countries such as Zimbabwe and Somalia. They are often highly resistant to the suggestion to formula feed, because of the stigma of bottle-feeding in communities where breastfeeding is normalized, and because of concern that this could "out" their HIV-positive status. The danger is that if these women are threatened with child protection services for breastfeeding, they most likely will continue to breastfeed in secret anyway, and that secrecy will make it impossible to counsel them on risk reduction measures like avoiding combo-feeding, dealing with cracked nipples promptly and so on. They may also be more likely to avoid medical services altogether which will make it harder to vaccinate the kids and so on. For this reason, medics in many countries are now advising pragmatism--counsel mothers to bottle-feed, but if they absolutely refuse, then you support them to reduce risk as much as possible rather than threatening to call in the social workers. It is essentially a "harm reduction" measure, like needle exchange programs for drug addicts; peds are not endorsing HIV-positive breastfeeding any more than needle exchanges are endorsing the use of illegal drugs.

An even harder case is represented by asylum seekers, because if an HIV-positive woman is encouraged to formula feed only to have her asylum application fail, she'll be left up shit creek; she will be forcibly repatriated to her own country where formula feeding is not safe, while her milk will have dried up. Thankfully, this loophole has now been closed (in the UK, at least), with breastfeeding now encouraged for such women until it is clear that they have the right to stay in their new host country. These common-sense and compassionate exceptions will help to safeguard some very vulnerable mothers and babies, so it's a real shame to see that some lactivists have chosen to take advantage of these to try and create deliberate confusion, implying that doctors have now given the green light to HIV-positive breastfeeding for all women in developed countries. In fact, doctors have done nothing of the sort.

Take the World Alliance for Breastfeeding Action (WABA) paper for example (7). Under "Current infant feeding recommendations for resource-rich settings," the WABA paper says:
"Their [BHIVA and CHIVA's] current published Position Paper 48 recognises in paragraph 3 that an HIV-positive woman already receiving triple ART, with a repeated undetectable viral load at delivery may, after careful consideration, choose to exclusively breastfeed for the first six months of her baby’s life. In such a scenario, the current guidance recommends: Continuing maternal triple ART treatment and short-term infant prophylaxis. Exclusive breastfeeding for six months, Frequent follow-up, Careful monitoring of maternal adherence until week after weaning. Monthly checks on maternal viral load and infant HIV status."
This is what BHIVA actually says:
"...avoidance of breastfeeding is still the best and safest option in the UK to prevent mother-to-child transmission of HIV. BHIVA/CHIVA recognise that occasionally a woman who is on effective HAART and has a repeated undetectable HIV viral load by the time of delivery may choose, having carefully considered the aforementioned advice, to exclusively breastfeed...While not recommending this approach, BHIVA/CHIVA accept that the mother should be supported to exclusively breastfeed as safely, and for as short a period, as possible. Thus, 3. In the very rare instances where a mother in the UK who is on effective HAART with a repeatedly undetectable viral load chooses to breast feed, BHIVA/CHIVA concur with the advice from EAGA and do not regard this as grounds for automatic referral to child protection teams...Breastfeeding, except during the weaning period, should be exclusive and all breastfeeding, including the weaning period, should have been completed by the end of 6 months. The 6-month period should not be interpreted as the normal or expected duration of breastfeeding in this setting but as the absolute maximum, since exclusive breastfeeding is not recommended beyond this period under any circumstances. The factors leading to the maternal decision to exclusively breastfeed should be regularly reviewed and switching to replacement feeding is advocated as early as possible, whether this be after one day, one week or 5 months."
Bit of a difference in tone and emphasis, huh? The BHIVA and CHIVA people are very clear that breastfeeding is a less safe option, but that one might consider allowing an exception for an absolute bare minimum of time if Mum really, really wants to breastfeed. The WABA spin makes it sound as though the docs have changed their minds and are all gung-ho for HIV-positive mums to get the boobies out. For what it's worth, the WABA paper is mostly a decent document with a good run-through of why breastfeeding makes sense for HIV-positive mums in poor countries. The problem is that, like a lot of lactivist literature, it can't resist trying to take things a stage further by twisting the evidence to make it look like breastfeeding is now the recommended approach for rich-country mums too. It isn't.

Smoke and mirrors
"IBCLCs can now feel more confident than ever before in supporting HIV-positive clients who express a desire to breastfeed. With certain safe-guards, including maternal adherence to antiretroviral (ARV) regimens which are mandatory in developed countries, the risk of transmission of HIV through breastfeeding can be reduced to virtually zero" states international board certified lactation consultant (IBCLC) Pamela Morrison in New HIV and Breastfeeding Resource from the World Alliance for Breastfeeding Action (WABA) in early 2013, which discusses the WABA paper mentioned above.

Now, that WABA paper is a little coy about the exact HIV/breastfeeding transmission figures--it kind of hides them away in the middle of one of the files--but when I found the relevant figures and crunched the numbers, it works out as follows: if you do everything "right" (proper ARV regime, exclusive breastfeeding with no formula or solids), your chance of transmitting HIV by age six months is about 0.74%, or approximately 1 in every 135 babies. That is not "virtually zero." It's a decent level of risk for a mother in a Cambodian stilt village; for a mother in a developed country who can formula feed safely it is absolutely unjustifiable, considering that we're talking about an incurable viral infection which requires a lifetime on a pretty unpleasant drug regime.

Shockingly, when two HIV-positive mothers themselves ask for advice in the Comments section on Morrison's article, Morrison continues to recommend breastfeeding to them without enquiring as to whether they are living in an area where formula-feeding is feasible, and even (in one case) after the mother has herself stated that she lives in the United States. We even see her advising a mother on nursing to 12 months--not six--which significantly increases the risk of infection above that 1-in-135 figure. Morrison's spin about reducing the HIV infection risk to "virtually zero" was picked up by several lactivist blogs and pages, including Best for Babes on 9 January 2013 which repeated the statement uncritically: "Big news for lactation pros and HIV-positive mamas!"

Why you should always read the original paper
Best For Babes is apparently not alone in writing odd headlines for articles they link to. On 29 January of the same year, the Kellymom Facebook page made the following post:
"The US Academy of Pediatrics Committee on Pediatric AIDS has come out with a paper saying breastfeeding should be accepted by HIV-infected women in the US under certain conditions..." 
followed by a link to the AAP's latest guidelines on Infant Feeding and Transmission of Human Immunodeficiency Virus in the United States. Now, this is what the guidelines actually say:
"An HIV-infected woman receiving effective antiretroviral therapy with repeatedly undetectable HIV viral loads in rare circumstances may choose to breastfeed despite intensive counseling. This rare circumstance (an HIV infected mother on effective treatment and fully suppressed who chooses to breastfeed) generally does not constitute grounds for an automatic referral to Child Protective Services agencies. Although this approach is not recommended, a pediatric HIV expert should be consulted on how to minimize transmission risk, including exclusive breastfeeding... 
and the opinion of the good doctors is and remains that "in the United States, where there is access to clean water and affordable replacement feeding, the AAP continues to recommend complete avoidance of breastfeeding as the best and safest infant feeding option for HIV-infected mothers, regardless of maternal viral load and antiretroviral therapy" due to the risks from infection and from drug penetration into the mother's milk. Anyone who does not actually click on the link and comb through the article (=85% of people on Facebook) is going to come away with the impression that doctors in countries like the States have now basically given HIV-positive mothers the green light. (Kellymom is no doubt fully aware that this is what will happen, and spins articles this way for precisely this reason.)

More recently, Kellymom enthusiastically heralded the arrival of a new issue of La Leche League International (LLLI)'s online magazine with a feature on "Breastfeeding for HIV-Positive Mothers." This piece contains all the usual smoke-and-mirrors stuff common to other lactivist resources on HIV. It makes vague references about exclusive breastfeeding being protective, while being coy about the fact that EBF is only protective in comparison with mixed feeding--when compared with formula feeding, it is still more likely to pass on HIV. It cites the Courtoudis study, which is the one and only (small) study where the breastfed babies were no more likely to get HIV that the formula-fed ones, but then completely fails to cite all the other studies (such as the Mashi study (8)) which all show that formula fed babies are less likely to get HIV. It repeats the misleading spin on the AAP's and BHIVA/CHIVA's stance on HIV which I described above.

It's disappointing to see Kellymom linking to this kind of thing. Then again, what can you expect from a website whose own HIV page is such a mess? The "HIV/breastfeeding" stuff on Kellymom consists of the following (see here and here):
(1) an article on ARV regimes for women in East Africa (irrelevant to the vast majority of Kellymom's readership);
(2) an article on the increased risk of transmission with mixed feeding in Zambia (again, irrelevant) which Kellymom has, confusingly, chosen to subtitle "Prolonged Breastfeeding Protects Kids From HIV" (the article does not say this);
(3) a broken link which appears to have once led to yet another set of recommendations aimed at the developing world;
(4) the bizarre "AnotherLook at breastfeeding and HIV/AIDS" page, which contains a Mothering Magazine article by the AIDS denialist (and, for that matter, germ theory denialist) David Crowe.

I think my "favorite" bit of Crowe's article--which is a nest of pseudoscience and conspiracy theories--is the bit where he decides to raise a glass to one Christine Maggiore for her brave stance against the evil establishment: "Christine Maggiore defied the authorities and, perhaps because she was a public figure with a wide support network, was able to continue to publicly breastfeed her two children." Readers, the well-known AIDS denialist Christine Maggiore is dead. Of AIDS. So is her daughter Eliza--quite probably because she consumed her mother's infected milk. I don't know if Crowe included this reference as some sort of unpleasant joke or because he thinks that his readers don't know how to Google stuff, but I really do have to wonder why on earth Kellymom thinks that it is remotely acceptable to have links to this kind of stuff on their website.

The swing back towards recommending breastfeeding for most women in developing countries is a huge achievement for public health and child survival. Nevertheless, the risk of HIV transmission via breastmilk remains, as does concern about the impact of ART drugs which penetrate the milk. Breastfeeding is therefore not recommended for women in developed countries with the exception of asylum seekers of uncertain status.
