Children are as vulnerable to the effects of ‘passive TV’ as they are to secondhand smoking, according to experts.
Casual exposure can harm their language development, making it harder for them to cope when they go to school, they claim.
The American Academy of Paediatrics has included warnings about ‘secondhand television’ in its guidelines for children aged under two.
Parents are more tempted than ever these days to rely on TV or computers to keep babies and toddlers entertained, the academy said.
But as well as discouraging the amount of screen-time to which youngsters are exposed, it cautioned against adults watching television with them nearby.
Studies revealed background TV reduced the time small children spent playing and caused their concentration to wander.
