A new study finds that sleep problems are more common in 3 to 5-year-olds who watch television after 7 p.m. Watching shows with violence, including kids' cartoons, was also tied to sleeping difficulties.
The American Acadamy of Pediatrics recommends no TV time for children up to age two, and no more than two hours daily for older children.
The government-funded study was released online Monday by the Journal Pediatrics.
