It is normal for babies to spit up small amounts from their feedings. But vomiting most or all of feedings is not normal. If your baby 5 months of age or younger has repetitive forceful vomiting shortly after feedings, is irritable and acts hungry, and has fewer wet diapers than usual, he or she may need to be evaluated for pyloric stenosis. Talk to a doctor about your baby's symptoms.

After surgery for pyloric stenosis

While your baby is in the hospital for pyloric stenosis, be actively involved in his or her care so that you will feel more comfortable doing it on your own after you take your baby home. Don't be afraid of holding or handling your baby. After one or two feedings of a clear liquid (glucose water), you may be allowed to give your baby breast milk or formula.

When your baby comes home from the hospital, give small, frequent feedings, according to your doctor's instructions. Your baby may vomit occasionally for the first few days after surgery. If vomiting is frequent or persistent (lasts beyond 2 to 3 days after surgery), call your doctor.

Complications from surgery to correct pyloric stenosis are rare. But call your doctor if you are concerned about the wound healing properly. A red or raised incision, with or without drainage, may indicate an infection.
