I'm really worried about my daughter Aradhya. She's been getting a fever two or three times every month for the last couple of months. We've seen different pediatricians each time, but they always end up prescribing antibiotics and antipyretics. The meds usually help for a bit, but then a month or two later, the fever's back. Recently, one suggested Septilin syrup, saying her immune system might be weak. Even after ten days on it, she got a fever again. Im feeling stuck and unsure of what to do next. Any advice?
