I am a big fan of PBS. My kids don't watch much tv, but what they do watch is PBS or the Discovery Channel's Life Series. They used to watch Noggin, which is now Nick Jr. Most of the shows are not very educational and often they are highly annoying. PBS shows on the other hand do problem solving, spelling, reading, science, etc. Sugar's favorite show at the moment is probably their least (practically speaking, although my kids can tell you just about anything about dinosaurs) educational Dinosaur Train.
