"I don't know why people think TV is good for babies. It's probably the way those products have been marketed," Schmidt said. "Although our study showed no evidence of harm, parents should be aware that infants watching TV may be at risk of obesity, sleep disturbances and possibly attention problems. We don't want this study to be viewed as a license for babies to watch TV because they won't be harmed. It might be that the effects don't show up until children are older."
Dr. Sara Hamel, a developmental behavioral pediatrician at Children's Hospital of Pittsburgh, called the new study "a very sound piece of research, and it looks to me like they did a good job of controlling the data for a number of variables that can influence child development, like parent education and income."
"This study answers a very specific question: For under 2s, does watching one hour or more of TV a day have an effect on cognitive outcomes? And, the answer is, no, being in front of the TV does not have an effect on some measures of language function and visual abilities," Hamel added.
A second study in the same issue of Pediatrics focused on whether or not adding violent-content labels to video games made those games more attractive to school-aged children and teens.
The warning labels had the opposite of their intended effect. Even for the youngest children in the study -- 7 to 8 years old -- a violent-content warning label made them want to play the game more, the U.S. and Dutch researchers found.
Here's what the American Academy of Pediatrics has to say about TV and toddlers.
