I've just been up to see my DS who was lying in bed, totally covered (past his head) by his duvet. We have bought him a light cot duvet as I am frightened he suffocates but he sleeps in normal size single bed (hes a big boy for his age).
He was soaked with sweat, bright red from head to foot and breathing really heavily. My DH says that he did this the other night as well.
Do I need to worry or is there some sort of automatic, inbuilt thing that will stop you suffocating yourself in your sleep, and do babies have it ??
