This document discusses children's exposure to and use of technology such as touch screens and mobile devices. While apps and screens provide learning opportunities, the American Academy of Pediatrics recommends limiting screen time to 2 hours per day due to potential harm. Some experts warn that overuse of technology could replace activities like imaginative play, reading, and family time. Teaching digital literacy and responsibility is important as more kids own phones and may face issues like bullying or sexting. Parents have differing views on whether technology helps children learn or if it exploits them.
