Screen time rules for kids under 12 are mostly performative parenting—we set arbitrary limits to feel in control, but the real influence comes from what we model and the content quality, not the minutes. I let my 8-year-old watch educational YouTube for an hour daily, yet I've seen friends with strict 30-minute caps whose kids still sneak tablets at night. Isn't the evidence on harm from screens mixed at best, with most studies showing tiny effect sizes?
