Some are for sure, but a lot of those shows hold up well for all ages. I don't put much faith in marketers to decide which shows are for what demographics. Better to see what lands for yourself. It helps when you're watching and discussing the shows with your kids too.

Some of them, Adventure time being a great example, can appeal to very young kids but they'll find new meaning in those episodes as they get older.

I think shows like Infinity Train, Avatar the Last Airbender/Legend of Korra, Steven Universe, and Samurai Jack will be better after a kid is old enough that Cocomelon wouldn't hold any appeal, but even at that age Sarah & Duck, Hilda, MLP, Craig of the Creek, etc could still be good. Just about anything that holds their attention and isn't Cocomelon is a huge win. If you'll enjoy it, all the better.

Thanks for the list anyway, I'll test some out on them!
