8 month sonJust today at 3 my boy has had a grey pale stool or poop. As time went we put him to sleep with his bottle and when he woke up  i sat hin up and he started vomiting all his formula up and even through his nasals. It was not and ordinary bloated vomit. Then again he started vomiting bt was dry heaving.
Might be just simple food innocence .... Don make him sleep with bottle in mouth...it may cause infection in stomach/intestine...continue feeding and if vomiting persists antiemetic... Give as much as fluid for him to Chat Doctor. .
