Vomiting is common in children. When vomiting occurs with diarrhea, it may be caused by a virus. Other infections, excitement, coughing and gastroesophageal reflux (GERD) may also cause vomiting. 

If your child is an infant and you have concerns with your baby not tolerating feedings / vomiting after feedings, contact your doctor. If your child has abdominal pain and / or fever with vomiting, also contact your doctor.

Too much vomiting can cause dehydration, which can be very serious. Dehydration happens when your child loses too much liquid.
