In Reply We thank Chen et al for their comments about improving the assessment of screen exposure in children. Our original study,1 published as a Research Letter, highlights the finding that young children spent most of their screen time watching television, even as mobile devices became increasingly prevalent between 1997 and 2014. The conclusions spur a variety of questions regarding children’s screen use in the digital age, including those raised by Chen et al, that were beyond the scope of our brief article.
