Another approach, that depends on your router/firewall, is to take a
look at the lists you can find here, for example:
If you can set up your router to block the IP ranges in these lists,
that would probably be more effective. The second you give your kids a
device that has a SIM card they will of course be able to bypass that
too since they now have an independent Internet connection, but they
can still be useful to block malware, phishing, spammers and other
ills on your local network.
I'm considering setting these lists up with pfblockerng on my pfsense
firewall. If your router can run something like OpenWRT you can
also fairly easily use these lists. Otherwise it depends on what your
router's firmware allows you to do.
