Question: how long should child stay home after vomiting?
Answer: Vomiting is typically short-lived. But, if your child vomits and is feeling unwell, it's best to keep him home until 24 hours after vomiting stops. See a doctor if vomiting lasts more than 24 hours, is accompanied by fever of 102 degrees Fahrenheit or higher, or if your child shows signs of dehydration.
