Home Care (Read "Call Your Doctor…" first):
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.
For Bottlefed Infants Offer Oral Rehydration Solution (ORS) for 8 Hours
- For vomiting once, offer ½ strength formula for 2 feedings, then regular formula
- For vomiting 2 or more times, offer ORS (Infalyte, KaoLectrolyte or Pedialyte)
- If ORS not available, use formula. Spoon feed small amounts: 1-2 teaspoons (5-10 mL) every 5 minutes
- After 4 hours without vomiting, increase the amount gradually
- After 8 hours without vomiting, return to regular formula. For infants > 4 months old, also return to cereal, strained bananas, etc. Normal diet OK in 24-48 hours
For Breastfed Infants, Reduce the Amount Per Feeding
- If vomits once, wait 1 hour, then nurse 1 side (to limit amount of feeding)
- If vomits twice, nurse 1 side every 1 to 2 hours
- If vomits > 2 times, nurse for 4 to 5 minutes every 30 to 60 minutes
- After 8 hours without vomiting, return to regular breastfeeding
For Older Children (>1 Year Old) Small Amounts of Clear Fluids For 8 Hours
- Water or ice chips are best for vomiting in older children. (EXCEPTION: severe diarrhea). (Reason: water is directly absorbed across the stomach wall)
- Give small amounts: 1 tablespoon (10-15 mL) every 5 minutes
- Other options: ½ strength flat lemon-lime soda, Popsicles or ORS frozen pops
- After 4 hours without vomiting, increase the amount gradually
- For severe vomiting, rest the stomach completely for 2 hours, then start over with smaller amounts
- After 8 hours without vomiting, add solids:
- Limit solids to bland foods for 24 hours
- Start with saltine crackers, white bread, cereals, rice, mashed potatoes, etc.
- Normal diet OK in 24-48 hours
Avoid Medicines
Discontinue all nonessential medicines for 8 hours. (Reason: usually make vomiting worse). Call if vomiting an essential medicine.
Contagiousness
Your child can return to day care or school after vomiting and fever are gone.
