Liz, don't worry about making her eat. Just keep her hydrated. Lots and lots and LOTS of liquid. Water, juice, even sucking on ice chips. Force aspirin on her too. And counter intuitive as it is, keep her lightly covered. Blankets and heavy clothes keep the heat in and make the fever worse.

Thus says the mother who nursed some scarily feverish children more times than I can count. A mother who can not type for shit. ;)

The danger with fever is dehydration. Once the fever goes down she will get hungry.
