I understand that YouTube has zero incentive for this but this is the kids mode I would like to have. A white-list of channels that I could negotiate with my kids. A couple of their favorite streamers that I also know that release material every other day, some weekly, so that the content can run out. "oh you watched YouTube all afternoon and you watched it all? Oh too bad, go out and play". And when I think about why YouTube never will add this feature, I get angry.

Edit:sure I could also add a couple of education channels but my kids would sooner go out and play.
