Such a timely thread, I tried starting one on this. There are so many factors to consider as children get older:
Only TV and consoles are in the living room, and we really don't want TV in bedrooms for anyone. No laptops etc either yet.
Adults (me & DH) not actually wanting to watch much tv in the evening, we just want some quiet reading / chatting time until our bedtime of 10-1030pm. We work in the same place so we see each other plenty!
Children aged 8 and 11 - the oldest one at high school and wanting the later bedtimes of his friends, the youngest not wanting to be left out and being a bit of a night owl anyway
Living in France where mealtimes and bedtimes are generally later (most families eat btw 7:30 to 8:30, bedtime seems to be around 10pm for children of this age). I would agree that there is a bit of a Brit thing about early bedtimes for children, not so much here. (My personal theory is that because French people work long days - due to the two hour lunches ;-) - and the children are in pre-school 0830 to 1645, 4-5 days a week, from the age of 2/3, the parents actually want to spend time with them in the evenings! They can also take an afternoon nap here until they are 5/6 yrs old).
Daily routine is all over the shop... DH and DS are in and out as they are teacher / student and only have to be in school when they are teaching / have a lesson. DS2 is more routine. I work pt, 3 days a week and different hours each day. So I usually watch all my adulty-zombie-horror faves while doing the ironing ;-) so we really like the evenings to be a bit more routine, it's hard work otherwise,
House size - we are in a 2-bed appartement, our DC share a (big) room so they don't really get alone time when they go there and just end up annoying each other. Letting them have tvs / watching tv on Ipads would solve this in one way.. but for us it's more important that these things are put away well before sleeping time.
We really haven't cracked it at all. It's very messy atm, we aren't back to school yet. The rules I hope we can put in place are:
Dinner at 7pm
No consoles / gaming / Ipads after dinner.
Family TV okay till around 8-30pm. Reading / quiet chat / board game until 9pm. Children encouraged to bed... they can read etc and put their lights out when ready (DS1 talks about wanting to stay up late like his mates: truth is he's a lark, so is usually zonko by 9:05pm and up at 6:30am ;-) and he has to be in school for 8am). DH and I to bed by 10pm.
So that boils down to a 9pm bedtime (but go to sleep when ready), and no tv / devices for anyone from around 8pm.
