Currently on the PBS Kids video apps and website, there are a bunch of Mr. Rogers' Neighborhood episodes streaming (for free, though you might need to use a U.S. vpn) to celebrate the 50th annivefsary of the show's U.S. debut.
I never had an opportunity to watch when I was little but I'm so happy that my toddler likes Mr. Rogers and the spinoff Daniel Tiger's Neighborhood. They are good and pure shows.
@cute_weeds it's an amazing show that is enjoyable for children and also very "this is how you be a good parent" for parents.
