Girls, can you tell me what to do? My daughter has a temperature for two days now and it's higher than 38 degrees both day and night, and doesn't go down. There's nothing else, like coughs or anything. The strange thing is that her father wants to call an ambulance, but she feels fine, she's not sick, she runs around and jumps when she has a fever. I'm confused.
