Upset Stomach
When a child has the flu they are more likely than adults to experience an upset stomach and the associated vomiting, nausea, stomach pain, and diarrhea. Therefore, it is especially important to keep children who have the flu adequately hydrated since they can become dehydrated after experiencing vomiting, diarrhea, or both. Sports drinks with electrolytes can be especially helpful as well as warm drinks such as caffeine free teas as they can help to soothe a sore throat and a dry mouth.
