Because she won't wake up in time the next morning.
I have a ds(6) & dd(3). DS needs 12 hours sleep a night, DD has never needed as much sleep (dropped naps sooner & used to wake earlier). They both go down between 7:00 & 7:15 and need to wake up between 7:00 & 7:15 the next morning.
Getting them to bed is OK, sometimes they have a story CD (doesn't seem to make any difference in actual falling asleep times). BUT DD just doesn't fall asleep, she plays with her toys and looks at her books for hours. Usually the bedroom light is turned back up, it has a dimmer switch.
She has been getting up in the evenings recently, but we can probably fix that as we did before for a sticker for not getting out of bed.
I don't think removing the light bulb will help as she will probably just open her bedroom door and use the hallway light to play by.
BTW I get up at 6:00, to get myself, packed lunches and school bags etc ready. So I am happy for her to wake up earlier and potter about with me.
Please help
