DS is 22 months old. Always slept well. Recently this is all out the window. He wakes several times a night and yells like a thing possessed.
He sleeps if we bring him in with us but I'm not confident on how safe that is so I don't really sleep.
I'm not sure what to do, I've considered getting him a duvet rather than his sleeping bag so he can decide if he's too hot or too cold. I've thought about moving him to a bed rather than his cot but I really don't know if any of the upheaval will help anything or make it worse?
Any ideas or tips?
