I'm tempted to block Youtube at the router (at least between specific times) because I find it is far more addictive for kids that I remember the TV used to be.

I'm tempted to block Youtube at the router (at least between specific times) because I find it is far more addictive for kids that I remember the TV used to be. The good thing about old TV with 4 channels is that most of the time it was boring, so you'd turn it off and go do something else. Kids TV would stop at about 6pm for the news (IIRC).
