Thankyou for choosing health care magic! This could be a normal vomiting
because of false feeding practice and on the other end it could be a Hypertropic pyrolic stenosis. In the later condition because of excessive growth of innerwalls of lower end of stomach (pylorus
) food cannot pass through the lower end and accumulated in stomach which gives rise to vomiting. Usually surgery is the option for pyloric stenosis
. I would advise you to see a pediatrician/pediatric surgeon for proper cure.
