My son is 4 years old. everytime when we make him drink milk, he start complaining of stomach cramp and vomiting. many times he ends in throwing out milk. what we can do?

A. it is ok for baby. There is no need to panic for this as it is normal in babies at this age . But if the problem exist for a longer time or you feel there is some other issue then a doctor should be consult near by for same .
