Home Care Advice for

1. Sleep: Help your child go to sleep (Reason: sleep often empties the stomach and relieves the need to vomit.) Your child doesn't have to drink anything if he feels nauseated.
2. For Bottlefed Infants Offer Oral Rehydration Solution (ORS) for 8 Hours
   • For vomiting once, offer ˝ strength formula for 2 feedings, then regular formula.
   • For vomiting 2 or more times, offer ORS (Infalyte, KaoLectrolyte or Pedialyte).
   • Give small amounts (1 teaspoon) every 5 minutes.
   • After 4 hours without vomiting, increase the amount.
