This is what I'm doing since the elsagate scandal, and a recent one where there was an ad of an obese dude jacking off (I'm in the middle east, this happened about 6 months ago).

I just automate the downloads of new youtube videos and let use jellyfin to watch it.

I don’t use youtube much, but I had to selfhost because the youtube kids app is fucking nasty. I have my pihole block youtube domains for my kid's device (firewall does captive dns/redirection of all dns requests to pihole).

My child likes dr binocs and brave wilderness.
