What can I do for my five month who has the flu?

Comfort rx. A prime worry with kid illness is their ability to keep up with their fluid needs when they feel bad.Vomiting, diarrhea & fever all driveup their fluid needs but they may not be interested.It is important to find some amount they can keep down even if its a tbsp every 20min.Tylenol (acetaminophen) for discomfort, gentil rocking & your comforting to help baby get past it.See dr if not wetting diaper or is worrisome.
If flu is confirmed- -tamiflu is a possibility if started early in the course of the illness. It shortens the duration of the disease, and in my experience (during the swine flu epidemic) prevents some of the complications as well, again, if started early in children with confirmed flu.
