Toddler Screen Use br Shows Explosive Growth, Says Study.br Conducted by researchers at the Eunice br Kennedy Shriver National Institute of Child br Health and Human Development, the br study was published in 'JAMA Pediatrics.'.br It found that the World Health Organization br recommendations for preschooler use of br screens — including television and computers — br is being exceeded in both the U.S. and Canada.br Over the course of two years, br 4,000 mothers were surveyed br about the screen use of their children br between the ages of one and three years old.br During this time, researchers br discovered that screen use increased br by three times from close to 50 br minutes to more than 150 minutes.br Our results indicate that screen habits begin early. This finding suggests that interventions to reduce screen time could have a better chance of success if introduced early, Edwina Yeung, Senior Study Author, via CNN.br According to the American Academy br of Pediatrics, children under 18 months br of age should not be exposed to screens br except for family member interactions.br Kids between the ages of br 18 months and five years should br have no more than one hour br a day of exposure to screens.
