Well, B is sick for the first time at 13 months; he has had a fever of 103-104 today.

I feel quite familiar with fever and know well that it is healthy and indicating that the body is busy fighting those invaders. However, most toddlers I know (through my friends) run fevers of 101-102 when sick. My daughter has always been a high fever runner. She goes from totally well to fever rising quickly to 104-106, which includes one incident of febrile seizure, and spikes every 3-4 hours with alternating medications. We know the drill, tepid bath, tepid rag on head and body, cool fluids.

I have been so fortunate; my kids are very healthy and seem to have great immune systems. The doctor has never been able to tell us more than some kids always run a really high fever, aside from last summer's possible explanation of cyclic neutropenia, which turned out to be just a scare.

Any BTDT parents or nurses that can give me a slightly more detailed explanation of why such high fevers. Thanks in advance.
