Phineus and Ferb. Whole family loves that show.
Kids learn things from cartoons that we may not think of as educational because we already know those things. Like how to treat a friend, how to manage stress, what to do when someone isn't as nice as they should be and more. All TV shows for kids aren't bad just because they may not teach colors or letters or science. Sometimes it's fun just for fun and that's okay too.
Any of the kids shows on PBS.
If you have the more expensive channel packages there are others like Sprout that come on at certain parts of the day.
