Sarah Stetner is proudly raising two young techies. Her sons, Gabriel, 3, and Isaiah, 6, are media mavens who know their way around an iPad—and almost every other device on the market. “Leapster, iPad, Wii, Xbox, computer, they do it all,” she says. The Stetners set media limits for ”noneduational” media and TV shows but not for learning-oriented video games and devices. “Those, they can play all they like,” Stetner says.
