dd1, age 5 can't get off to sleep at night any more. Used to do 7pm - 7am regularly, since tiny but for the last 2 weeks she's been awake (in bed) til 8.00 or 9.00. It's too late for her as she only started school full time in September. I gave her hot milk at 9.00 and all seems quiet now. Any ideas how we can solve this?
