Thanks for the data, and I agree with your other comments in general. Articles about these studies pretty much always oversimplify the calculus. I'll add that besides paternal involvement, maternal stress over societal pressure to breastfeed if it's not working out for some reason can certainly be worse for the overall outcomes than the loss of breastfeeding. I'm glad that this study apparently included socioeconomic factors, but my instinct is that there are many other factors being left out. What are the correlations with maternal work schedules, time spent bonding with the child in other ways, etc? My guess is that other potential impacts on IQ and long-term outcomes not considered by this article also correlate with the breastfeeding/formula decision.
