Dd has not been able to drop off to sleep for some time now. Sometimes it's 10.00 before she can get to sleep and I do feel she is tired in the day. There is nothing going on at home or at school to worry her. I've tried music playing, lavender oil, hot milk, getting her to count sheep. I'm running out of ideas. Anyone had this problem or can offer solutions. She gets put to bed at 8.00 pm and her brothers go to sleep right away but she can't seem to.
