My daughter is 4 months old and I stopped breast feeding her at 7 weeks old. She has been throwing up all of her formula's since. She has been on like 4 different formulas. She is on Nutramigen now, which is a hypoallergenic formula. She is still throwing this one up but not as much as the others. I was talking to someone and they told me to try breast feeding her a little. Milk is still in my breast and she will take it, but on one of the ducts where the milk is coming out it has a pinkish color. Is this blood or what? Is it ok for her to eat from? She seems to want it but I don't want her to get sick from it either. Does anyone have any suggestion?
