Stomach flu or gastroenteritis is an incredibly frustrating illness to deal with. It is super contagious. It can cause major and dramatic symptoms immediately, but for some children it can cause ongoing lingering symptoms for a few weeks after.

Dehydration is a math problem. Dehydration can happen because of illness, over-exertion, or the environment.
