What time does your teen go to bed on a school night and the weekend?
We (the whole family) are in bed with the lights out at 9 on the weeknights. We were letting our teens stay up till 11 but my son was falling asleep in class and just not doing well with his attitude or in school. So we put our foots down and he goes to bed when the rest of us do and he is doing so much better.
On the weekend we let them stay up until 2 a.m. and no later. He just does so much better the more sleep he gets.
