My sister was a vomiting baby. All you had to do was touch her and she would vomit, so many people commented how they had never seen anything like it... It was really hard to go anywhere as she would 100% of the time vomit over herself and anyone within a 5 mile radius The most practical advice anyone gave my mother was just to watch her dehydration. If her lips arent plump and you cant keep any fluids down take her to the hospital. She didnt grow out of it like most Drs said, she is now 30 and still vomits at the sight or smell of anything bad. Some people just vomit, allot... Persist with fluids and stand back..

Good luck
