Lisa wrote in about a baby who seems to develop painful blisters from breastfeeding. Two questions come to my mind - Is it the breasts, or the milk? Since you are having mom eliminate dairy due to dad's dairy intolerance, I infer that you suspect it's something in the milk. Could be, however, one 'test' would be to use mom's finest out of a container rather than straight from the breast. That would allow you to look at the issues separately. I don't want to assume anything...so I'll ask... What kinds of soaps, moisturizers, preparations is mom possibly using on her body/breasts (or cleaning and/or fabric softeners on her clothes) that could cause the skin of her nipples to become 'caustic' to the baby? Good luck! Margaret Ann Margaret Ann Paxton, LLLL, IBCLC Lexington, VA
