Vomiting in Babies Under 12 Months

Vomiting in a baby is the forceful emptying of stomach contents through the mouth. It is different from the effortless small amounts of milk that come up with normal spit-up.

Viral infections are a common cause. Reflux, feeding problems, food reactions, intestinal blockage and other illnesses can also cause vomiting in babies.

When to see a doctor

Contact your pediatrician or another healthcare professional if:

  • Your baby vomits repeatedly, especially if they are very young.
  • Your baby drinks much less than usual or has fewer wet diapers.

Call 911 or get emergency care if:

  • Your baby vomits blood or bright green fluid.
  • Your baby has severe dehydration or a very swollen abdomen.
  • Your baby is very difficult to wake or has another life-threatening symptom.
