My son has been running a fever since last night, and his body is burning all night. It's honestly the first time we've had this happen. Because of the fever, he couldn't sleep, waking up every 30 minutes to an hour. He needed to be re-laid down, rocked, and given ibuprofen and a warm towel. At 7 pm it was 38.3, then he fell asleep at 10 pm. He woke up at 37, now 37.9, it's rising again. I don't know what to do. Maybe call an ambulance? I'm sick too, probably infected...? Not as active as usual, just sleepy,
