My son is 8 and a 1/2 months old and since he was about 4 months old he has screamed when he poops. His bowel movement is not hard so I am not sure why he screams. When I say he screams it is an ear piercing scream, I asked his doctor at the last 3 appts. and he says that there is no worry, but if it was still happening at his 9 month check up to bring it up again (which I fully intend to do) I am not sure what I can do to ease the pain or if there is an underlying concern. It shouldnt be a matter of a stool softener, I am just not sure. Also if it helps he is on soy formula, he has been since 1 week old.
