Can a child want to sleep because of fever? He slept for 2 hours, woke up crying, we're holding him by the hands only now he fell asleep again, when I want to sit or lie down, he cries and wants to be carried, it's because he has no strength anymore ? It seems like the fever is gone, but before going to bed, I can't check, he cries, he's crying at night. I noticed strange twitches in his arms and legs while sleeping, as if seizures, but he was sleeping during that time. I wrote to my pediatrician, call an ambulance, says to go to private only on Wednesday, we will go.
