I think the simplest method is to monitor a DNS log and any of the children's devices could be monitored via a DNS log. For me, I just want to know when I need to have a conversation with them rather than scold or punish them based I what I see in the DNS log. I have a pfsense router on my network, and monitoring the DNS requests on the network could help flag when someone needs some 'loving parental guidance'. I'm honestly very nervous about this era of my parenting responsibilities, my eldest being 10 years old.
