I know it's the school holidays, but I'm surprised at the time a lot of ds, 11yo friends seem to go to bed.
Ds goes up about 9pm, usually asleep by 10pm. I let him watch a film in my room or read until he's ready to go to sleep, as it's the holidays I've let him watch the laptop a few times.
His phone is still buzzing now at gone 11 with friends ringing and texting, he's been fast asleep since about 9.30pm. A couple of the dc were bragging that they stayed up until 4 in the morning.
Aibu to think it's too late. Occasionally ds would stay up really late for example if we are on holiday, or if he had a sleepover, but generally asleep for 10pm is late enough isn't it?
