 So here are those four things. The four norms that we can all coalesce around, all parents, all schools, we can do these if we do them together. No smartphone before high school. Give them a flip phone or a phone watch. It doesn't have a browser on it. That's the key thing. Or social media platforms. The second rule, no social media before 16. Just don't let them open accounts. Don't let them download the app.
