When I was growing up, we were not allowed to watch TV at all during "school nights" (any night that was followed by school the following morning).
We were not allowed to play video games under the same rule, and my folks refused to buy us a console in the first place (although I bought a nintendo when I was 16, and then sold it a few months later).
When it was nice out, we weren't allowed in the house except for meals.
I can remember resenting some of these rules growing up... But now, I'm very thankful for them as they forced creativity and activity, and I'm better off for it.
Now, I have two young children of my own (3 and 5 years old) and it's time to start thinking about how I will implement such rules in my own household. (edit: we of course have a lot of rules in place already... what I mean is that my kids will soon be in school [so "school nights" rules can begin to exist] and they're beginning to be old enough to want TV time and be interested in video games that they see at their cousin's houses etc.)
I'm curious to hear others' take on these topics.
Thanks,
