Hi,
{{hugs}} to you, I know this is a scary time for you, as it is for all mommies with sick kids, but I would say as long as his fever is not going over 100 (or even if he does, no higher than 102) then he is alright! just make sure to keep as much liquids as he'll drink going thru him so he doesn't get dehydrated (one way to tell he's dehydrated is he stops going potty) and give him some children's fever reducer. other than that there isn't much else you can do.
if your really concerned contact your pediatrician, but from what you are saying he would probably tell you the same thing as I've said.
good luck, and hang in there!
