My 2.5 yr old ds has started waking in the night. And howls, he screams for a cuddle, and even when he has had several will not calm down. He gets hysterical. I am really not sure how to deal with it, having tried all sorts. Have tried bringing him to our bed, lying down in his bed, putting him back in bed and leaving the room. We leave the landing light on now, but he still seems to wake in a panic, and will not be comforted.
