Most vomiting is caused by a viral infection of the stomach (viral gastroenteritis) and may last up to one week. Vomiting may be present with a combination of symptoms that include diarrhea, fever, and generalized abdominal cramping.
Treatment is focused on supportive care and adequate hydration. Replacement of fluids is important in the vomiting child. Do not give your child ANYTHING to eat or drink for 30-60 minutes after vomiting.
Your child will not become dehydrated by waiting, in fact giving their bellies time to rest and then offering small amounts of clear liquids is the best way to ensure adequate hydration. A teaspoon every couple of minutes will suffice then gradually increase the amount as it is tolerated.
The vomiting is usually greatest in the first 24 hours. If your child does not eat any solids for several days, don’t worry! As long as they are drinking liquids and staying hydrated. Their weight will return to normal when their appetite returns.
