Screening out: What are parents doing to limit screen time for young children?

About 25 percent of parents who have children aged two to five say their children get three or more hours of entertainment screen time a day, well beyond recommended limits, according to a new poll from the University of Michigan.

n the latest University of Michigan Mott Children's Hospital National Poll on Children's Health, a little more than half of those parents do try to set some limits by location: banning media devices from places like the bedroom or at mealtime.

In 2013, the American Academy of Pediatrics issued updated guidelines to recommend limits on screen time for children. The AAP discourages any screen time for children less than two years of age. For older children, the AAP recommends no more than two hours daily. The AAP suggests keeping media devices out of children's bedrooms, keeping family routines like mealtime screen-free, and setting screen-free days for the whole family.

The poll found that 53 percent of parents are following recommendations that children's entertainment screen time be limited by location. Twenty-eight percent said they use a combination of location and time limits.

But 13 percent said they do not limit entertainment screen time or locations for their young children.

The poll was administered in March 2014 and reflects the responses of 560 parents of children 1- to 5-years-old.
