Another question. My daughter gags after every feeding ? That is, she can't calm down until she gags. Only if she really wants to sleep can she fall asleep further. But otherwise, she has to hold her upright for half an hour after every feeding ? My explanation has already said goodbye to me. And by the way, she's gaining weight normally. Has anyone had this too?
