My three year old is constantly burping.

Gas is air that gets trapped in the gastrointestinal system and needs to be released. Burping is one of the ways for parents to help their baby get rid of that gas. When gas bubbles get stuck in your baby's stomach, they can cause a feeling of fullness and discomfort. Some of the causes for burping in children may includes the following: - Intestinal obstruction Hiatal hernia Superior mesenteric artery syndrome Consuming carbonated drinks Gum chewing Eating too fast Drinking too fast Lactose intolerance
