My 11 year old says she can't get to sleep, she gets so worked up about this and cries for hours. Have tried explaining this will not help... have bought her a torch so she can read quietly and then try again, she doesn't go on her iPad or anything before bed. She is totally irrational about it then stands at the side of my bed refusing to go back to her own! She says nothing is worrying her and is happy during the day.. any suggestions?
