The book is footnoted like mad. But the assertions of mother-baby breastfeeding issues are my own assertions and no, I have no hard evidence for it.

But she does talk about how certain cultures deal with various issues. She mentions preemie babies a little bit (I'm only half way through, so maybe there's more to come?) and hasn't gotten to special needs at all yet.

In general, the history of medical practice for 'non-standard' babies has been horrific.
