Hi there I understand your concern... It would have been better if you had mentioned baby age here....It's common for babies to vomit often in the early weeks...continues vomiting can be due to indigestion,recurrent gastroenteritis,Even a prolonged bout of crying or coughing can trigger this reflex. So you may see quite a lot of vomiting in your baby's first few years....it can be due to pyloric stenosis as well... I would suggest you to consult nearest pediatrician for clinical examination and evaluation they will do the needful.
