Just teach them how to use the internet safely and properly. Not to say their age and their address, not to add random people on discord, stuff like that. If you isolate your kids from the internet, then at this point in time, you’re kind of isolating them from a decent chunk of human culture, which from personal experience (anecdotal, not very useful, I know), is a terrible idea. I was raised Mormon, I know how restricting access to things goes for kids. They’ll end up buying a phone off of a friend with less of an idea of how to use it safely. Maybe check their youtube homepage once in a while, make sure it isn’t slop, ask them about what they’re doing on there, answer any questions they have. Might wanna filter some stuff before middle school though. Block gore sites, those tend to fuck people up quite a bit.
