Hello girls! The baby is 2 years and 7 months old. The temperature rose to 38.5 yesterday evening. It started to scratch at night, we called an ambulance, they said nothing useful and didn't do anything, left and didn't take him back. Now there's a fever, he doesn't want to eat or drink, he lies down and that's it. What should I do? Panic in the whole house?
