Yeah Pixar does it a lot, and Bluey, and Peppa Pig a little. But it's really uncommon in kids TV shows. 99% of them are straight up dross just for kids with no accomodation for parents.
That's why Bluey is so popular. It's the only good TV program for adults that kids will also watch. (And I agree it's only super popular for adults, kids are way more into trash like Blippi.)
Oh I disagree, my kids like Blue a lot more than Blippi. But they like better-but-still-dross like "Spidey and His Amazing Friends" about the same as they like Bluey, whereas their parents like Bluey about an order of magnitude more :)
