June 28, 2023

If you have a child or toddler vomiting with a fever or a child or toddler with diarrhea and a fever, you may not know the cause or whether or not to be concerned.

Both vomiting and diarrhea are common symptoms of food poisoning and the stomach flu, among other common ailments. So how do you know if your child’s pain is severe enough to require an emergency department visit? 

If your child has a low-grade fever and/or vomits once, call a doctor to be seen the next day. 

Fever and vomiting in toddlers and children

In a child or toddler, fever and vomiting in and of itself may not be cause for concern. However, symptoms such as a child or toddler high fever & vomiting may warrant a trip to the ER. Visit the pediatric ER if your child or toddler's vomiting & fever shows any of these additional symptoms. 

  • The child is younger than 3 months old
  • Repetitive vomiting
  • Not urinating or wetting diapers
  • Lethargic
  • Inconsolable
  • Vomiting toddler or child with fever higher than:
    • 100.4 degrees for children younger than 3 months old
    • 102.2 degrees for children older than 3 months old

Similarly to vomiting, diarrhea and fever in a toddler or child may be an outcome of common ailments. However, when the child or toddler diarrhea and fever is accompanied by these symptoms, you should seek emergency care.
