My 3 yr old has recenlty started waking up freauenlty through the night. He cries and whines. He has been getting in my bed. We have never co slept with him. But when he is in my bed he tosses and turns and keeps me up all night. I dont know whats wrong with him. Tonight he didnt wven want pjs on he wanted to sleep is his undies but finally let me put a shirt on him. It gets cold back in this room. But he is very hot blooded. Sweats like crazy... idk what to do. I got maybe 3 hours of sleep last night and its wasnt even 11 when he started tonight. He didnt go to bed till 930...
