Infant acid reflux, more accurately known as gastroesophageal reflux, is a very common problem. Infant acid reflux occurs when the contents of the stomach go back up into the esophagus.
Although infant acid reflux most often occurs after a feeding, it can happen anytime your baby coughs, cries or strains. Most babies who have infant acid reflux are healthy.

Pyloric stenosis is a rare condition in which a narrowed valve between the stomach and the small intestine prevents stomach contents from emptying into the small intestine.
