Have had a problem with my DD not going to sleep until 10pm at the earliest recently, she doesn't mess around, goes to bed at 8pm, reads quietly for 15mins after I have read to her and then lies there quietly unable to sleep for ages. I am trying not to get overwrought by this and worry her into worrying about not sleeping iyswim, but I am very anxious as she now complains in the morning that she is too tired. Have tried warm drink and banana, lights on, lights off, waking her up at 7am instead of 7.30, letting her read until she falls asleep (was still reading at 10pm last night!), not letting her watch TV, letting her watch TV but nothing seems to work.
Is this usual for a 7 year old? Is there anything I can do to help her?
