I have just read another thread that says 11 year olds go to bed sometime between 8-9pm. My DS1 is 13 in Sept and currently goes @ 9pm lights out @ 9.30, although this seems to be getting later and he moans that his friends all go later, am I being unreasonable seen as he is going into year 8 and almost 13 (I feel he needs that much sleep to be fresh for school). My DS2 is 10 and goes to bed @ 8pm lights out 8.30, again I think this is reasonable but he says his friends go at 10pm!!!
