You are exactly right. My husband is a doctor. He learned almost nothing about breastfeeding during his medical school training. They told him it was better, but he learned nothing about technique or how to help women do it sucessfully. He learned far more from me and our four children.
I have done some breastfeeding counseling. I am appalled at what some mothers are told by doctors and nurses. I suspect that in most cases of "unsucessfull breastfeeding" there is nothing wrong except poor advice.
That explains why my doctor, female no kids, had such bad acdvice. Our area has a few lactation consultants, who were WONDERFUL.
