I can say that I definitely received LESS than 12 hours of education on breastfeeding in medical school. In fact, I can't recall any type of teaching on the subject at all. No lectures during the first two classroom years. Nothing during my Pediatrics rotation as a third-year student. Nothing at all. And I graduated fairly recently from a good school (5 years ago). I'm sure doctors who specialize in Pediatrics or Family Medicine do go on to get some type of education about breastfeeding during residency training after medical school, but at least at my school, we learned nothing at all about the subject during medical school. I'm sure it varies by school, but some schools teach nothing at all about breastfeeding.
:( That is actually pretty sad. It could have been an average statistic.
You would think they would have even just one lecture about how breastmilk is made.
