I noticed that my 17 month old daughter developed a small breast bud under her right nipple 3 weeks ago. I took her to the doctor and they said that since there were no other symptoms and it moves freely around we should not be concerned but to keep an eye on it. Yesterday I noticed that my daughter's other nipple (the one that is flat) has a small dark hair growing up through the inverted part of the nipple. It is very slight and can only be seen in bright light so I am not sure exactly when it grew. It is black but not coarse to the touch. I took her to the doc again and they said that the breast bud is normal and they have never seen a hair like that before but they think she is ok and to call if anything changes. Otherwise she is in good health. She has been on soy milk for a little over four months prior to that she was on soy formula. I just took her off it last week as I read it could effect estrogen levels in kids. I don't know if soy could do this or not. The pediatrician was very non committal on the topic of soy. They said that I could talk to an endocrinologist but that most likely I would be told to wait and see what happens. I am concerned about a greater health issue, the hair on the nipple is what my main concern is.
