I do not want my children to drown in media. The way the world is going now, I don't imagine that to be an easy task.
The few things I can do? No TV in the car or minivan. Limits on portable video game systems and setting up appropriate playing times. No eternally plugged in iPod earbuds.
And also, no wheelies. They don't have anything to do with media, I just can't stand those things. At least not on kids who run uncontrolled through crowded public places. :P
