My baby boy is 3.5 months old. what can be the reason for vomitings soon after the feeding ? Is that a serious problem ?

A. hello spitting or vomitting curdled milk is normal in kids at this age and try to burp after every feed and if baby is vomitting too much then it is better to check with your doctor and your doctor will be able to guide you better on examination of the same and advise you accordingly
