When my daughter started kindergarten, the teacher asked parents to sign a pledge limiting screen time at home, and it made me wonder where we draw the line between protecting kids and letting them explore the digital world. Some parents enforce strict no-phone rules until high school, while others hand toddlers tablets for educational apps—both approaches seem to have trade-offs. What has been your experience with setting boundaries on children's technology use, and do you believe there's a universally right balance between screens and real-world play for kids under 12?
