My 2nd and th grandsons had extreme vomiting and the Dr. at Childrens Medical Hospital in Dallas put them on Lactaid , it is a lactose free milk and it really helped. The vomiting almost completely stoped also the Dr said to put a small amount of cereal in the milk, this was when grandson 4 was about a month old.. Good luck , I know this is a really scary thing to have happen.Especially if this is your first child. Hugs and prayers for you and your family. Nana Katie
