A tween who will only engage with screens is often one whose other domains of life feel less competent, less socially safe, or less rewarding. Screens deliver reliable competence, leveling up, mastery, social feedback, that the rest of life sometimes does not. Understanding what specifically the screens are delivering, social connection, mastery, escape, stimulation, points toward what needs to be built, not just limited.
What is it about the screen stuff that works for you? I am genuinely asking, not setting up to take it away.
