My 3 year old daughter has had a low grade fever (99-101 degrees) since last Thursday. It s been over a week now. I have had her to the Dr. and they have her on Azithromycin and she is on day 3 of it but it still persists. No other symptoms that I can find: Eats like a horse, good attitude, sleeps well, naps well, plays well... says not pain anywhere, no urine infection, not teething that I can see. I m getting worried! Should I take her in again? Thanks!
