In most households, this is a challenge for most parents, placing limits on screen time. In homes with TVs, computers, electronic games and all the rest, 10 to 11--year-olds now have access to an average of five screens and they regularly watch 2 or more at once.
The TV is on over there, ipads are on, ipods are on and if you want actually constantly show them and put a foot on them, they will be quickly happy and sit there all day.  
Robert Blair doesn't have much to worry about, he is a martial art instructor and his children spend more time on the mats than the couch.
