I'm super concerned with idea one person suggested of waiting until it hits 105...organs will shut down and fail at that temperature.
I always judge a fever by where a temperature normally runs; not everyone is 98.6. Personally I normally run at 97.2 so when I'm around 101 I know I'm pretty sick, and it rarely gets that high so when I have a fever at all I'm concerned. My sister normally runs at 99.4, her average, so she doesn't worry until she's around 103 or so. My son can generally handle 102 fine but rarely goes over that so if it were 102.5 or 103 I would be concerned; point being it just depends on the person, we all "tick" differently.
Alternating doses of Tylenol and Ibuprofen/Motrin is the best way to bring it down, though as another mother said fevers are natural occurrences in the body and happen for a reason. If she seems ok, just keep her comfy. Maybe she is teething. If so she may also get a runny nose and diarrhea, it'll go away. If its a virus it'll just have to run its course, however if the fever persists for more than a couple days you should suspect infection and take her to see the doctor.
Best wishes for he speedy recovery :)
