  • Acetaminophen helps decrease your baby's pain.
  • Do not give aspirin to children under 18 years of age. Your baby could develop Reye syndrome if he takes aspirin. Reye syndrome can cause life-threatening brain and liver damage. Check your baby's medicine labels for aspirin, salicylates, or oil of wintergreen.
  • Give your child's medicine as directed. Contact your child's healthcare provider if you think the medicine is not working as expected. Tell him or her if your child is allergic to any medicine. Keep a current list of the medicines, vitamins, and herbs your child takes. Include the amounts, and when, how, and why they are taken. Bring the list or the medicines in their containers to follow-up visits. Carry your child's medicine list with you in case of an emergency.

Follow up with your baby's healthcare provider as directed:

Write down your questions so you remember to ask them during your visits.

Feed your baby as directed:

Your baby may be able to eat his usual amount of breast milk or formula.

Wound care:

Care for your baby's wound as directed. Keep your baby's abdomen dry for at least 2 days. Then you may put your baby in a tub bath. Carefully wash the wound with soap and water and pat it dry. The medical tape will peel off on its own. Do not pull it off.

Avoid crowds of people:

Keep your baby away from crowds while he recovers from surgery. Avoid people who have a cold, the flu, or other illness.

Contact your baby's healthcare provider if:

  • Your baby has a fever.
  • Your baby vomits more than 2 times in 1 day or vomits more than 2 days in a row.
  • Your baby is irritable and fussy, even after pain medicine.
  • Your baby's wound is red, swollen, or draining fluid.
  • Your baby's symptoms return.
  • You have questions or concerns about your baby's condition or care.

Seek care immediately or call 911 if:

  • Your baby is vomiting and cannot keep any liquids down.
  • Your baby has any of the following signs of dehydration:
    • Dry mouth or cracked lips
    • Fast heartbeat or breathing
    • More irritable or fussy than normal
    • Urinating little or not at all
    • Sunken eyes or fontanels (soft spot on the top of the head)
