Hi, My 9 month old is running a fever, mainly at night of 101 to 102 for the past two weeks. We went to the Dr. last Monday and there is no sign of infection. She was very fussy and lethargic the following Friday, Saturday she was normal, Sunday she was lethargic and feverish again. Hardly no sleep last night but lots lots of crying no matter if we were holding her or not. What could cause this other than infection (ear, nose, throat is clear) and is there more we can do other than give fever reducer?
