Hi, little one, yesterday started vomiting after every feeding, before it was only 2 times in all time. We registered with pediatrician, but I think maybe we should go to the hospital? Because feeding - vomiting or jumping and there is quite a lot of it. When did you start vomiting? After all, I thought if it was good from birth, then it wouldn't be anymore.
