Dd1 (9.5) has always had a late body clock, ie goes to sleep late, gets up late. However lately it has becoming worse and worse and I'm getting worried.
I like her in bed by 8-8.30pm and she reads till 9pm or so. But she's often still awake much later than this - sometimes past 10pm. She's impossible get up in the morning of course but once she's had breakfast she's normally ok.
She just seems to have a lot of energy in the evening and can't get to sleep. She gets enough exercise btw - she does a lot of ballet which seems to energise her even more rather than make her tired.
