Next time you bring your kids in for a checkup, don’t be surprised if the doctor asks about their tastes and entertainment. The American Academy of Medicine suggested last week that doctors work with parents to evaluate how much TV kids watch and what they see, what video and computer games they play, which websites they visit on the internet, whether they play, website they visit on the Internet, whether they view R-rated videos with the company of their parents, what music they like and what books they read. Doctors are worried that kids who spend too much time in front of the tube don’t get enough exercise and can become overweighted. The Academy is also concerned that the message the kids get from entertainment media can make them more violent and sexually active. The Academy recommends that children under age two not watch any TV. "Children need activities to stimulate the brain during the first two years of life," says Doctor Marien Barren, who chairs the Academy’s Committee on public education. "They need feedback and socialisation," she says, "Older children should watch TV in a common area. Their bedrooms should be electronic-media-free zones where they could have a quiet place to read, study, play or just relax."
