Screen Time for Children

I'm doing some research for a curriculum project of articulating social and emotional developmental standards for students ages three to fourteen.

I found the excerpt below about media and screen time in the Washington State Early Learning and Development Benchmarks guide:
"Inappropriate use of media/screen time (e.g. television, videos, comptuter and video games) can negatively impact a child's social and emotional development by contributing to aggressive behavior, desenitization to violence, nightmares, and fear of being harmed. The American Academy of Pediatrics (AAP) recommends discouraging screen time for children younger than 2 and encouraging interactive activitie that will promote brain development (e.g., playing, talking, singing, and reading together). For older children, the AAP recommends that caregivers limit children's total media/screen time to no more than 1 to 2 hours per day of quality children's programming."
