My daughter is about two weeks old and keeps throwing up. It's not after every meal but frequent enough that is scares me. The doctor believes it's just an overactive let down since she is gaining weight and has wet/poopy diapers. She said it could also be another condition that she would need surgery for but does not think this is it since it's not every feeding as well. I am EBF. Does anyone have any experiences with this happening with an overactive letdown?
