A study published in the Journal of the American Medical Association found that children spending two to three hours daily viewing screens such as iPads, smartphones and televisions were more likely to exhibit delays in reaching three-year-old and five-year-old developmental milestones. The study tracked almost 2,500 children from birth. Researchers wrote that, to their knowledge, this was the first study to find a “stable association” between screen time and developmental delays.
