After a week of being normal my daughter's fever has returned. It started last night at just 100 and was normal during the day. Tonight it is 102.6. She is fine and in good spirits, no diahrea, no cough, no runny nose, no pains - just sleepy and not hungry in the evening when the sun goes down and the fever goes up. Unfortunately, this happened on a weekend and her new pediatriacian can not be reached until Monday. Should I try a remedy or wait? I'm puzzled by the lack of other syptoms.
