This is key, in my experience. I've told my kids that if they catch me scrolling shorts or reddit, they have the right to confiscate my phone. A big part of instilling the values I referenced above is embodying them myself. (obviously, but it bears repeating).

This is important too. There's so much genuinely great media out there - TV shows, video games, movies, books. It's not that I don't want my kids to experience that stuff - I just want them to learn how to focus on the stuff that's quality rather than the stuff that is slop.
