My 4 year old, nearly 5 is rarely asleep before 9pm. She shares a room with her 2 year old sibling and whilst she won't actively try and wake her up it means I can't quite leave her to own devices. She doesn't wake up for school before I wake her up at 7:45, on a weekend we'll wake her up by 8:30. I wondered whether her late nights were because she was overtired and giddy but now I'm just wondering if she is not really tired till getting on for 9pm. Anyone else have a child on a similar time table? How do you manage your evenings? What if they share a room???
