Stomach Bugs in Children: What Parents Need to Know
June 16, 2026
What is a Stomach Bug?
Stomach bugs are most commonly caused by viruses. The typical symptoms are vomiting and diarrhea, and your child may also have fever, belly pain, runny nose, cough, sore throat, or headache. Children with feeding tubes may gag, retch, or not tolerate feeds rather than fully vomiting.
When to Call Your Doctor
Call your doctor or Imagine Pediatrics right away if your child:
- Is an infant under 12 months with vomiting or diarrhea
- Has blood in vomit or stool
- Has yellow or green vomit
- Has severe or worsening belly pain
- Has a swollen, bloated, or tight belly
- Is vomiting with headache but no diarrhea
- Has trouble tolerating feeding tube feeds
Signs of Dehydration:
- No tears when crying
- Dry lips or tongue
- No urine for 6–8 hours
Go to the ER or call 911 immediately if your child:
- Is unusually limp or unresponsive
- Is breathing differently than normal
- Has dusky, gray, or blue skin color
- Is having a seizure
How to Treat a Stomach Bug at Home
Most stomach bugs are caused by viruses, so antibiotics won’t help. Here’s how to support your child:
- Start with gut rest. If your child is vomiting, pause all food and drinks for one hour to let the stomach settle.
- Reintroduce fluids slowly. After one hour, offer small sips of clear fluids (like Pedialyte or diluted juice) every 5–10 minutes, about 2–8 ounces per hour depending on your child’s weight.
- Watch for hydration. Urinating at least every 6–8 hours is a good sign your child is staying hydrated.
- Manage fever and pain. Use acetaminophen (Tylenol) — ibuprofen can worsen nausea. Check with your care team for the right dose.
- Don’t worry about food. It’s okay if your child doesn’t want to eat for a few days. Fluids with salt and sugar (like Pedialyte) are enough until they recover.
If Your Child Has a Feeding Tube
Call your provider to create an action plan. A typical step-down approach looks like this:
- Replace formula with Pedialyte at a slow, continuous rate for 24–48 hours
- Transition to half Pedialyte / half formula at a continuous rate for 24–48 hours
- Transition to full-strength formula at a continuous rate for 24–48 hours
- Return to your child’s normal feeding plan
