Hiccups come up frequently at pediatrician visits, and are a common source of worry for parents. But they shouldn’t be. In fact, they may actually have a purpose in newborns, and be a way of teaching them how to control their breathing.

Newborn babies have immature GI systems which are naive when it comes to digestion. As they start to feed, there is an adjustment process, and gas is a normal byproduct of that process. Gas is a result of an imbalance between the air that goes into the system and the air that comes out of the system.
