My 3yo has a fever of 102.5 she is sleeping. should i wake to give medicine or is it better to let fever do its job? she has a slight cough.

Fever: If she is getting rest i think it is best to let her sleep.

I never: I never wake a kid for fever meds. Sleep is natural treatment by itself.The only meds I would wake a kid for are timed prescription meds (like for seizures) or antibiotics ( and rarely for these). I also prefer ibuprofen to acetaminophen because it doesn't need to be given as often.
