Mark Zuckerberg's sister writes children's book on joys of switching off technology Ms Zuckerberg worked for her brother's company until February 2011, and has since founded her own social media firm named Zuckerberg Media and set up a blog, Dot Complicated, to deal with dilemmas of the digital age. In it, she shares her tips for parenthood, and discusses how to limit the technology available to her son Asher, two. "My tech 'rules' for Asher are simple because he's so young," she writes. I try to limit iPhone and iPad screen time to when we're outside the house. I use these devices to distract him and prevent fussiness at a restaurant or on a long plane ride, for example. At home, I prefer Asher engage in creative and active play with us; however I'm always on the lookout for fun and educational apps for him. In the end, our goal is to teach our children to use technology responsibly, rather than technology dictating their lives.
