The analysis is actually quite different. Bottle feeding has massive advantages for division of labor among parents. I did all the night feedings for my first two kids so my wife could get some much needed sleep. She didn’t have to pump which is often so much trouble it’s not worth it. Moreover, they now associate me with being the nighttime parent, so when they’re sick or having trouble sleeping I’m the one they come to, not mom.

Losing that flexibility would be worthwhile only if there was strong evidence that breastfeeding had advantages that can’t be replicated with formula. On that front it should be noted that the vast majority of GenX and older millennials were formula fed, as breastfeeding rates plummeted in the 1970s and 1980s. If there was a massive impact from that it would have been apparent.

Breastfeeding seems to have epigenetic[1] and microbiome[2] advantages that are unique.

It is associated with less GI infections, ear infections, asthma, lower blood pressure, lower cholesterol and risk of type 2 diabetes.

"Generation X and millennials are in worse health than their parents and grandparents were at their age.

That's the conclusion of a new study that looked at markers of physical and mental health across the generations."[1]

Of course, there could be many reasons for that.

Again, that'd be an argument against breastfeeding, given that millenials were born at a peak time for breastfeeding. Really, though, it's probably got nothing to do with breastfeeding.

Yes evidently many children grow up fine on formula. So given that the effect of breastfeeding is capped, it’s reasonable to choose to optimise for other factors such as practicality, father-child bonding time and so on.

As a counterpoint I’ll say that to the extent that the transfer of antibodies prevents or reduces infant illness, that is a win in the dimensions you describe on its own. A sick infant is both wildly impractical and hard to bond with.

For example, in this interventional cohort study with breastfeeding promotion [1], ”the percent of children having pneumonia and gastroenteritis declined 32.2% and 14.6%, respectively, after the intervention.”

Does breastfeeding negatively impact father-child bond ? I find it highly unlikely. We do know for a fact that it’s better for health.

I’m talking about the logistics of men taking on more of the woman’s traditional caregiver role in couples where both people work. In that respect breastfed babies (or even babies who drink pumped milk) are much more dependent on their mothers. With our first two, who were bottle fed, it was more convenient for my wife to go on a business trip in the first year or two than me. My third was breastfed for six months, and he was highly reliant on my wife in a way the others were not.

And the science shows that the health benefits are minimal.

You keep saying the health benefits aren’t there, so you need to provide evidence.

All the nurses, midwives, and doctors I know declare otherwise

Exclusive breastfeeding (not exclusively feeding breastmilk, but exclusively breastfeeding) would to a certain extent, yes.

Exclusive breastfeeding means the mother's presence is essential, she has to be available most of the time as the primary care giver. Due to the way modern societies and nuclear families work, it's reasonable to assume that it's unlikely both partners would take long term leave to be with the infant, or that the father could be there anywhere near the same amount of time as the mother. So the infant would have far more time to bond with the mother than with the father. Whether this time alone is enough to guarantee a stronger bond is probably worth a separate discussion.

In early stages of life the mother’s presence will never not be essential.

It just feels weird to run this random experiment on my current child. Is evolution/biology wrong, and this processed stuff from the store better?? You'd have to have shocking amounts of studies to convince me it's better to have a baby eat that fake stuff than a mother's breast milk.

And finally, I think it's incredibly selfish to argue about equitably splitting feeding times, at the likely expense of your child's health and growth.

Young adults and men seem to be less healthy than ever. Plummeting testosterone, crazy rates of allergies, increased suicide rates, high depression.... But your right, if feeding them processed junk was bad, we'd see signs of it by now.

The father can do everything except breastfeeding, so there’s no reason (except illness) to divide labour on exactly the thing that evolution built the mother to do.
Re:Do breastfed children have higher IQs? The answer is anno... by tptacek on Saturday July 16, 2022 @12:04PM (#32119354)
Who gives a shit how evolution "built the mother"? It also built us to walk the plains and jog slowly after ruminants for hours on end to feed our tribes. In 2022, what the mother probably needs to do is get up in the morning reasonably refreshed and get in to her office.
Re:Do breastfed children have higher IQs? The answer is anno... by blub on Sunday July 17, 2022 @07:55AM (#32126038)
The WHO and any local health org worth its salt cares. Parents that want the best for their baby do. The more appropriate question is who wants to ignore the medical consensus and why.

Of course some women can’t breastfeed and they deserve support. But downplaying the benefits of breastfeeding because it may hurt the feelings of some mothers is not the way to go.

It’s disappointing but not surprising that you’re saying that mothers need to go to work in the US. AFAIK in many parts of Europe they take many months off (often 6-12) to spend time with the baby. For some of them, it’s the only time in their life that they’ll get the chance to do that. Work can wait.

Why do mothers need to work in the US in the first 6 months of their baby’s life? Why can’t one of the richest countries in the world pay them to stay at home?

The rest of the thread discusses, and I think mostly debunks, the notion that breastfeeding is vitally important for infant health. I'm just here to take potshots at appeals to the naturalist fallacy, that if nature "designed" something some way, it's important for us to continue honoring that design. No, it isn't.

As for parental leave: why not pay men to stay home? Why the presumption that women must be the ones to sacrifice their careers? Because "breastfeeding"? That's a pitiful justification.

Re:Do breastfed children have higher IQs? The answer is anno... by blub on Wednesday July 20, 2022 @02:40PM (#32170294)
Thankfully nobody's likely to be reading HN for advice on breastfeeding, debunked or not. :-) They're going to look at the recommendations of the WHO, their country's equivalent or talk to their doctor or midwife. All of which would recommend breastfeeding, since that's the current scientific consensus. The EU in particular highlights the importance of breastfeeding for at least six months.

I'll say this though - breastfeeding can be a complete mystery for new parents and doctors are often clueless about it. A competent midwife which is familiar with the typical issues is priceless. It's good that there's formula available for those cases where the woman can't breastfeed or the baby is having difficulties and the parent's don't know what to do and can't find competent help.

In the EU, the parents get a number of months which can be split between them. Fathers in Germany for example take a few months off. Because breastfeeding, because moms often want to spend time with their babies and yes, sadly often also because they earn more.

Mothers probably don't need sleep, right?
Re:Do breastfed children have higher IQs? The answer is anno... by blub on Sunday July 17, 2022 @08:03AM (#32126069)
There are cots which attach to the parent’s bed and special blouses which allow for easy breastfeeding without undressing.

The whole process is as simple as dragging the baby over, taking one breast out and bringing them near to it. The baby will take care of the rest.

Mothers do get sleep, including during the day together with the baby. There are solutions out there for many frequent or rare problems. A good midwife and experienced mothers in the family / circle of friends are priceless.

A few hours of extra sleep can be the difference between a functional and non-functional household.

People don't often seem the grasp the variability of the difficulties that different babies can throw at parents. It really is just harder for some parents than others.

Grow up. People are different than you. You don't know their life and you obviously haven't experienced enough of the world to recognize how difficult it can be for some mothers to get enough sleep to function. Especially if she is recovering from a difficult pregnancy and/or delivery. Add to that the high incidence of post-partum depression and losing sleep can be all the more damaging.

As our very pro-breastfeeding lactation consultant wisely told us with our first child, "Breastfeeding is best, but your child will benefit so much more from a mentally well and rested mother."

Re:Do breastfed children have higher IQs? The answer is anno... by rastignack on Saturday July 16, 2022 @02:45AM (#32115785)
Breastfed children tend to have less stomachaches. When your baby cries because he cannot digest the formula, you arguably lose a big part of the benefits.

Also breastfeeding is much more convenient when traveling.

I think using formula was heavily promoted as a way to establish equality, and many people turned a blind eye on the drawbacks for the sake of progress.

It’s a good thing that we are now prioritizing babies’ health.

Maybe on average, but specific cases can vary wildly. Some foods that the breastfeeding mother consumes can cause issues. Milk, soy, and caffeine are known troublemakers - but good luck finding out which one is the source of stomach issues for your baby!

It’s not that hard. Breastfeeding mother should no drink more than a cup of coffee per day.

Regarding milk, avoiding it for a few days and checking for improvements is enough to see if it’s the culprit.

Re:Do breastfed children have higher IQs? The answer is anno... by jjeaff on Saturday July 16, 2022 @05:26PM (#32122122)
I worried about things like this when I found out that we would have to formula feed our baby. But then I dug into the literature and found that the effect in most cases, while statistically significant, were very minor. Usually just a few percentage points different. And that's not to be interpreted as "kids who were formula fed were 2% sicker or scored 1% lower on tests". It's more like, out of the group of kids we studied, some formula fed kids scored higher and others scored lower. But it averaged out to a few points lower.

There are so many other, much more important factors in raising a healthy kid. The breastfeeding vs formula is hardly worth the brainpower.

This is an absurd case parent-shaming. Most parents already have a high level of anxiety that they are not doing enough for their kids. Let's not shame them for getting sleep so that they can be awake and have better interactions with their children.

Also, outright calling someone a bad parent because you don't agree with one of their methods is unnecessarily cruel.
