"When I asked many families if I could film them relating with their kids about these issues, so often they would say no. I learned just how private parenting is. And this is a problem. I believe we need a Rules Revolution. We need to spread the message that having screen time rules helps kids succeed. The myth that ‘kids just need to learn for themselves’ is just not possible—screen time can be just too darn tempting." • Delaney Ruston, mother to Tessa, 15, and Chase, 18, doctor, and filmmaker behind Screenagers.
