My 1 year old has fever of 100.8 what drinks and food should I give him instead of milk?

Why avoid milk ? Milk is a comfort food for most 1yo and i see no reason to with hold it during fever. If s/he is vomiting or otherwise having digestive issues, i might omit it for a while, but not for long.
Clear fluids! Gingerale, soup (chicken), jello-these are all good and are unlikely to cause stomach issues with fever! plenty of water!
