The academy recommends now that for children 2 to 5 years of age, screen time should be limited to one hour per day. Infants aged 18 months and younger should not be exposed to any digital media. This is hugely important for their brain development. Parents are in charge of setting limits on digital media for kids and teens six and older, the academy says. The pediatricians agree that digital media should never replace healthy activities. “The environment of media has changed today,” Chassiakos said. Many aspects of digital media are positive: it can be interactive; it facilitates communication; it allows people to create. Kids often view class lecture notes and do homework through a screen, she said.
