hello so ever since my son was born he ha been throwing up more than noraml babies and childern do. when he coughs, crys, burps and sneezes he may throw up. the acid from his belly runied his 4 front teeth so as a one year old he had some dental work done. even when i try to give him medicine when hes sick he throws it up. he gags very easy. i have taken him to 3 differnet doctors over time, and he has had xrays and uper gi test and lower bowel test, they have said nothing is wrong, but there is something wrong. im having to clean out more car and his carseat daily, and his teeth have began to discolor again. daycares arent wanting to keep him beucase they think hes always sick or had the flu, no one undertands, but i defintely know something wrong and its becoming embarssing for my son, and he trys to hold it in becuase of other peoples reactions to him vomiting. please tell me waht is going on? my son was breast fed and it was like my milk was souring inside of him, and now he drinks cows milk and water and he still throws up???
