I am dealing with one of these. The mom is on her second baby and always put the baby to the "bad" breast first. Baby #1 became unenamored (screamed) with the "bad" side gradually over the first month or so also, so I was suspicious. Upon examination, I noted that the mother's nipple on that side was unusually shaped (her pediatrician labeled it "deformed"; it lies folded over when first uncovered), almost bisected, what I might call a "raspberry" nipple. I hand expressed on her at three weeks postpartum; she was already severely involuting, and milk came out in only three places regardless of many changes of position and massage. Mom has no unusual breast shape, surgeries, biopsies or conditions to blame this on twice in a row, and her experience of milk coming in and mild engorgement were equal for both sides. It is my theory that she has the ability to make milk, but that due to possible aberrations of the nipple shape and function, lack of transfer resulted in failed supply over time. I did the rare thing and ditched that breast all together; we are putting baby to the "normal" breast and building the supply there for one-sided nursing. Does any of this sound applicable/familiar? I can't believe the number of weird and difficult things I've come across lately. -Lisa ****************************************************************************** Lisa A.
