For some women, breastfeeding is easy, convenient and wonderful. Once the authors controlled for the mother’s IQ score, the effect of breastfeeding was even smaller, at 0.5 points. Looking across all the available studies, I find that the best data on the relationship between breastfeeding and IQ doesn’t support a link. In a sense, none of this argues against the claim that “breast is best”. Many of the benefits women hear about are speculative, or do not show up in the best data.
