PBS Kids isn't bad either (I end up seeing a little of it at times when I'm waiting for one of the news programs to come on and it's in that between time just before it starts).

PBS Kids, Discovery Channel, Animal Planet, Food Network (ok, so the food isn't always the most balanced, but it's interesting and I'd be watching it anyway. And if you're watching a show on cake, you'd know beforehand to specify to a kid that this is treat food and not everyday food), the do it yourself shows.... there's a lot of programming out there that isn't mind numbing for kids to learn from.

That's if I have cable tv when I have kids
