Transcript for Setting screen time rules for kids in 2019
A runner's pack. I don't call it a fanny pack. Honey, it is. Okay. Big dilemma for so many of us. Is it time for a social media detox? Becky Worley is back with that, and I think we all know the answer to it. Yeah. Kids and screen time, especially for modern 13-year-old girls, they dominate their interactions with peers and their parents. Asking a group of ten girls to log off social media for two whole weeks, that might be the first step to a year with more balance. We're in California. Ten girls from a few different schools. Eighth and ninth graders who volunteered for a major challenge. I can't wait. Reporter: No social media for two weeks. They mostly use Instagram and Snapchat. New research suggests that screen time is associated with anxiety in teens, and child and adolescent psychiatrist, Jodie gold says so. Losing the messaging functions within these apps. They are vital for making plans and arranging rides. I have more people on Snapchat than I have, like, phone numbers. Reporter: Another concern, milestones. What am I going to do if, like, my friend has a birthday and I can't post that? People are -- They're going to be so mad. Reporter: Here is the challenge. Two weeks, no social media whatsoever. Delete the apps right now. I can't. Oh my gosh. Oh my gosh. Reporter: We asked the teens to record video diaries throughout the experiment. I have been able to just put my phone down and just listen in. I can actually sleep a lot better without being on my technology a lot. Reporter: After two weeks, they reinstalled the apps and we gathered to talk through the results. Show of hands, who thinks they slept better? Who got into fewer arguments with their parents? They said they felt a little out of the loop. I missed out on so much. I didn't know Pete Davidson and Ariana grande broke up. Reporter: When they hung out with friends not part of the experiment -- They would be sending each other pictures and I was, like, why don't we do something? I was, like, we're getting off our phones and we just listened to music and talked and we had so much fun actually and I learned so much about them. The upside from Taing a break from social media is you have time to do your homework and spend time with your parents and be mindful of your experiences. Reporter: They were more present in real life. I'm more cautious and it showed me I don't need social media at all. I did perfectly fine for two weeks without it. I fought so much less with my parents. I have gotten so much more done and I feel like it kind of in a good way made me feel like I was a little kid again. It made me feel, like, you know, not worrying about stuff as much. I learned so much from these girls and from talking to counsellors and a neuroscientist. Let me break it down and get practical here, Amy. Kids hate limits. Kids want limits, and we as parents, we have to help them. So it sounds like we as parents need a recipe for success. Absolutely. So the first thing is talk to them at a time when things aren't hot and bothered and you're all mad about screens. Actually ask them to watch maybe this piece or some of the other reporting we have done on kids and screens. Your kids have incredible insights to what they need and what's bothersome to them. They can say, do screens make you feel, you know, compelled? I have done that. Because they end up being in a bad mood after they sit on their screens for a long time. Yes. They know what they need and want and then after they do that, next step, get a media contract. You can go to commonsensemedia.org and download a contract and it will talk about when, where and how much time kids can spend on screens. So we have karis and Sandra, mom and an 11-year-old, is that right? They're signing a contract. Any big issues? Snapchat. Is that the one? Yeah. Working to limit maybe the Snapchat involvement for long periods of time. That's the second step. Final step. You have to layer in limits and basically automate it. Use technology to fight technology. You can do Thi your wi-fi router, parental controls there to shut devices off. You can do this with apps and the one that we like is circle with Disney. This is -- dsney is an investor in this company, and we have to disclose that, but this is amazing for the devices you're using. Gaming consoles -- Inside and outside of the house? Inside and outside the house. You put the app on the kid's phone and it shuts it down when they have hit their limit. It's tough to be the screen police 24/7, impossible actually. Parents give up because it's so much rough work. That has happened with me. Becky Worley, thank you so much.
