CINCINNATI — Screen time was a perennial concern for modern parents well before the COVID-19 pandemic began. Now, with nearly half of Ohio school districts conducting classes only over the internet and most in-person socialization sharply limited, it’s even more of a catch-22. How much is too much? How little is too little?Children’s Hospital pediatrician Dr. John Hutton studies the effect of technology on children and adolescents, and even he isn’t sure.“Screens have become such a huge part of kids’ lives in a very short period of time that we really don't know a lot of the longer-term effects,” he said Friday.The American Academy of Child and Adolescent Psychiatry has found some correlation between extended screen time and trouble with sleep, mental health, and school performance.Hutton said it’s likely not all the same. Using a laptop, smartphone, or tablet for school, as most Ohio children have done since March, doesn’t necessarily have the same effect as using the same device for social media or games.Still, he encouraged families to closely examine the amount of time they and their children spend using screens every day. He recommended setting aside screen-free times, such as during meals, and encouraging battery-free activities such as reading or playing outside as a healthy complement to children’s daily routines."I think it's very important,” he said. “I think every family is going to have something that's realistic for them. I think there's definitely not a one-size-fits-all."This story was first reported by Josh Bazan at WCPO in Cincinnati, Ohio. 1591

CHULA VISTA, Calif. (KGTV) - After hours of listening to public comment, the Chula Vista Planning Commission decided to table and continue an item that would bring a new recreational storage facility to the city's Eastlake area. The proposed facility would store 80 to 100 vehicles, like boats or RVs, on land between Eastlake High School and Antigua, a gated town-home community.Homeowners begged the planning commission to not accept the plans for the facility saying it would be an eyesore for their properties and lower their property values. The property manager of Titan Storage also made his case before the commissioners, citing the need for the facility in a part of town that is growing quickly. RV owners asked the commission to consider accepting the plan because they say surrounding RV lots are full, forcing them to store their vehicles across town. Ultimately, three commissioners said they could not support the plan as presented and voted instead to continue the item to a future date, giving the storage company time to present a revised plan. So far, no date is scheduled for the next public hearing on this issue. 1143
