Some doctors are concerned that anxious parents over treat harmless fevers when actually, most fevers are a positive sign that the immune system is doing what it is supposed to do, fight infection.
A reminder, if you grab something to treat a child's fever, don't be fooled if the bottle says "children's aspirin," because if it says aspirin, it should never be given to a child. "If a child has a fever and they're given aspirin, they run a risk of developing a syndrome called Reye's Syndrome, which is fairly uncommon but can be fatal, Kevin Rodowicz, M.D., a Pediatrician.
The American Academy of Pediatrics recommends not treating a fever under 101 unless the child is visibly uncomfortable. But the AAP says if the fever does not go away within 24 hours, then you should seek medical advice even if the child has no other symptoms.
