Dh often gets home late - around 8.30/9pm, sometimes later. My 2 younger dds are 9 (nearly 10) and 5 and are usually both settled in bed by 8.15 ish, although they take longer to get to sleep.
When dh comes home they rush down to see him, which of course is lovely, but by the time they've had cuddles, a chat etc, they're wide awake again and it's ages before they actually fall asleep. Hence tired for school in the morning.
But I feel a bit mean saying they can't come and see Daddy, they haven't seen him all day. Would it be unreasonable to set a rule that they're not allowed down after lights out? Dh, by the way, is easy - of course he loves to see them but understands that they need their sleep for school.
