Our 7 year old daughter has had a 101.8 to 104.3 fluctuating temperature for the past 3+ days. This evening the temperature dropped like a rock to 96.1. How concerned should we be? We tested it oral (3 time), rectal (1 time), and for good measures underarm (1 time) with similar results. At what low temperature do you call in a doctor, especially given she has had a pretty high temperature (104.3) 90 minutes earlier (yes, we gave her the recommended amount of Tylenol)?
