The first five years of a child’s life are a magical time of rapid development that is foundational for their later cognitive, social, physical, and behavioral health. As families worldwide navigate the integration of digital technologies and media into daily life, researchers and clinicians continue to investigate the impacts of screen use on all facets of development, from infancy through late adolescence. Children and Screens has summarized insights from current research and experts in the field to help parents and caregivers of infants and very young children learn how to build a foundation of healthy brain, neural, and social development — and help families determine how they can intentionally and most beneficially incorporate media use into their child’s life.
