DS will be 10 in September. He's normally in bed by 8. We read a story together until 8.30. He often then struggles to get to sleep before 9.30 and is tired during the day. He wakes naturally at 6.30-7.
We have no TVs / phones in bedrooms. He nearly always has a wind down time before bed. I wouldn't be worried about his sleep routine if he wasn't complaining that he can't get to sleep, and of being tired.
What time do most kids of this age go to sleep?
