It is generally well known that the eager new parents tend to overthink everything and overdo everything they can think of (stroller type? formula vs breast milk? daycare amenities? nursery wall color?).

This list strikes me as a good example of why a LW listserv / shared research about this is useful. Yeah, stroller type won't make much of a difference, and nursery wall color won't either. About half of important life outcomes are heredity, and you've missed the opportunity to change that.

But breastfeeding? We're talking ~8 points of IQ, here. Breastfeed your children, and do it for as long as you can stand.

I am pro-breast feeding but skeptical of the IQ claim. Can you link the study?

My guess is they compare the avg IQ to the average of a selection of people who breast feed.
I would expect this to be subject to selection bias.

Why are you in favor of breast-feeding at all?
It is correlated with socio-economic status, and thus with all good things. But every correlation I have seen corrected for parental SES goes away, including IQ. Decades of randomized controlled studies demonstrate no effects. On the positive side, I must admit one cluster-randomized (n=31) study of IQ in Belarus, but I am not impressed.

Because when in doubt go with convention.

I think there is a lot we don't understand.

Now if my wife found it bothersome perhaps we would not follow convention, but so far it she likes doing it. From a fathers perspective it is vastly superior due to the ability to leave a bottle out of the refrigerator for 6 hours instead of 1.

Is that a serious question? Because when you add "at all" and then list sudies which only address IQ benefits it seems like you think that is the only potential benefit.
