Nausea and Vomiting, Age 11 and Younger
Vomiting occurs when a child's stomach contents are forced up the esophagus and out of the mouth. Although nausea may accompany vomiting in adults and older children, children younger than age 3 are usually not able to tell you if they are having nausea. Most of the time vomiting is not serious. Home treatment will often ease your child's discomfort.
