DD6's clock still hasn't gone back ... any ideas?

[paranoidmum]

DD 6 yrs now waking up 5.45 am on the dot every morning - as opposed to 6.45 before clocks changed.

No change to routine otherwise, bed at 7.30. Didn't matter so much in half-term, but now back at school so tired ... and waking DS up to play. Any ideas apart from wait til spring ? !!

Can you get her an alarm clock and tell her not to get out of bed til it goes off? Say she can read or play quietly in her bedroom if she wakes, but not disturb anyone til the alarm?
