what causes reflux in babies
Babies get reflux because the muscular valve at the end of the food pipe, which acts to keep food in the tummy, hasnât developed properly yet. This means that when your babyâs tummy is full, food and acid can come back up.This can cause him to bring up small amounts of milk (possetting) or even vomit.abies get reflux because the muscular valve at the end of the food pipe, which acts to keep food in the tummy, hasnât developed properly yet.
