My little boy will be two weeks on Tuesday and he has already projectile vomited in his short life. Is this normal? On Thursday evening we decided that I was going to EP so he gets bottle of breast milk and we supplement 2-4 oz per day. When he vomits, he immediately acts hungry again and I never know if I should feed him or not but I do. He never seems bothered by his vomit so I hope it is just his stomach learning how things work. Have you experienced this before?
