Hello Dr, my baby is 1 month old & she is going on vomiting the milk immediately after every feed ,. How long she will vomit the milk like dt what to do for dt

A. ​​Spitting up is normal and completely harmless for most infants. When the spitting up or vomiting becomes too frequent, your child may have Gastroesophageal Reflux (GER). This reflux is a result of an immature digestive system and the poor closure of the valve (ring of muscle) at the upper end of the stomach.
