My 13 and 14 year old DSs never seem tired in the evening like I am. I'm fit to drop by 10pm but I don't want to go to bed before they do. (I'd not sleep anyway). At the mo the compromise is they are in bed reading even if not sleeping. (Screens go off at least 1/2 hour before lights out)
Am I too controlling? Part of my reluctance is not trusting them I guess.
I'm a single mum- I have a partner who stays over a few nights a week, which adds another "issue" to bedtime!!! My privacy!!! 
School nights are easier to manage/justify but during the school holidays it's different and they e both told me they don't fall asleep til after 11.
What do others do?
