Parents should limit kidsâ screen time to 2 hours a day: American Academy of Pediatrics. Mark Risinger, 16, checks his smartphone at home in Glenview, Ill. The American Academy of Pediatrics updated its recommendations for teens and technology on Monday, suggesting parents limit kidsâ screen time to no more than two hours a day.

As children reach ages 2 to 5 years, the recommendations are similar to when they are toddlers and encourage limiting screen time to one hour or less of high-quality programming.
