Not sure what to do!
DD has never needed lots of sleep.
Everyone promised me when she started school she would change. She didn't.
She goes to bed at 8pm. She is almost always still awake at 9.45 (unless she is ill).
She isn't a problem per se. She stays in her room. When she is tired she calls down good-night to us.
Do I need to do anything?
I mean you can't force someone to sleep can you?!
She gets up fine in the morning and is not grumpy (usually!)
