My kids are allowed 30 minutes of tv each weekday. Currently all three of them are glued to Electric Company. Which, for me, is WONDERFUL! Electric Company starts at 5pm. Perfectly timed. Miss Mae gets home from school around 3, one of them needs to be dropped off at dance by 4, and we're home by 4:15. Then the other two have 45 minutes to play and/or pick up their rooms. The rule is - can't watch tv until the rooms are picked up. Works like a charm.
Here Muffin and The Boy are glued to the couch. (Miss Mae's at Dance)
Now I can make dinner in peace. :)
