Until a week ago my ds slept almost perfectly - 7.30 to 7ish nearly every night hardly ever waking up. After xmas he had 3 nights at inlaws house with h and slept very badly there (as he usually does). H had to take ds to bed with him eventually every night. This has continued since he got back and he gets hysterical when left in his room (says he's scared of the dark so i leave the landing light on - makes no difference) so he ends up coming to bed with me and there i don't sleep much either. I just don't know what to do - i've tried sitting with him, ignoring him but nothing works. Anyone have any ideas?
