Parents of infants and toddlers should limit the time their children spend in front of televisions, computers, self-described educational games and even grown-up shows playing in the background, the American Academy of Pediatrics warned on Tuesday. Video screen time provides no educational benefits for children under age 2 and leaves less room for activities that do, like interacting with other people and playing, the group said.

The recommendation, announced at the group’s annual convention in Boston, is less stringent than its first such warning, in 1999, which called on parents of young children to all but ban television watching for children under 2 and to fill out a “media history” for doctor’s office visits. But it also makes clear that there is no such thing as an educational program for such young children, and that leaving the TV on as background noise, as many households do, distracts both children and adults.

“We felt it was time to revisit this issue because video screens are everywhere now, and the message is much more relevant today that it was a decade ago,” said Dr. Ari Brown, a pediatrician in Austin, Tex., and the lead author of the academy’s policy, which appears in the current issue of the journal Pediatrics.

Dr. Brown said the new policy was less restrictive because “the Academy took a lot of flak for the first one, from parents, from industry, and even from pediatricians asking, ‘What planet do you live on?’ ” The recommendations are an attempt to be more realistic, given that, between TVs, computers, iPads and smartphones, households may have 10 or more screens.
