Good evening everyone. I need your help!!! My son is 8 months old and has no teeth at all. Yesterday he had a fever of 39 degrees, today it's been three days with a fever. I'm trying to lower the temperature with candles ciprofloxacin and ibuprofen syrup, the temperature goes down but then rises again in two hours. The ambulance was called, they didn't really help. Yesterday the pediatrician came and said about the teeth, at 8 months old he should have 8 teeth. She prescribed tablets and calcium. His gums are swollen on top and bottom now, I don't know what to do. We bought everything according to the prescription. Today there is still blood from his nose ?
