Yes I thought the vomit may be related to the speed and supply. Didn't really think of it as oversupply though... Although I am very full in the AM, and I did stop pumping cause they are fuller and spurting more a day or two after I do. Sometimes I push her to feed more cause I worry she hasn't had enough if she's on,y feeding for a short while, but I should stop doing that cause it probably makes it worse. I just worry she won't put on enough weight if I don't.
