not many people know this, but you can use both ibuprofen and acetominofen medications at the same time, so if you have given tylenol and the fever is not reducing, you can also give motrin, the only thing you have to watch is that you leave 8 hours between the motrin and the next dose of motrin and the same with tylenol, 104 is what the docs say is the cut off to bring the child in.
i know all this coz my son had a fever of 104 last week.
get pedialyte popsicles, cool baths and a fan blowing on him.
my son also threw up with his fever, apparently there is something going around - it only lasted 48 hours then he was fine
