I have a 9-yo. We experimented with time limits &c, but that just leads to endless discussions on the size and applicability if thise limits.

Now he has a mostly-airgapped Thinkpad (with music, kiwix, music-experimantation stuff, programming things, and onlyoffice), and doesn't know the ipad's passcode.

The laptop has nftables set up so that only an ssh connection to my laptop works, which I use to update it, add content, and occasionally unblock it, when necessary.
