Silicon Valley Nannies Are Phone Police for Kids
Silicon Valley parents are increasingly obsessed with keeping their children away from screens. Even a little screen time can be so deeply addictive, some parents believe, that it’s best if a child neither touches nor sees any of these glittering rectangles（不停闪动的长方屏幕，只带手机）. These particular parents, after all, deeply understand their allure（魅力，带有神秘的色彩）.
But it’s very hard for a working adult in the 21st century to live at home without looking at a phone. And so, as with many aspirations and ideals, it’s easier to hire someone to do this.
Enter the Silicon Valley nanny（保姆）, who each day returns to the time before screens.
From Cupertino to San Francisco, a growing consensus has emerged（成为共识） that screen time is bad for kids. It follows that these parents are now asking nannies to keep phones, tablets, computers and TVs off and hidden at all times. Some are even producing no-phone contracts, which guarantee（保证） zero unauthorized screen exposure（暴露，接触）, for their nannies to sign.
The fear of screens has reached the level of panic in Silicon Valley. Vigilantes（自告奋勇者） now post photos to parenting message boards（论坛） of possible nannies using cellphones near children. Which is to say, the very people building these glowing hyper-stimulating portals have become increasingly terrified of them. And it has put their nannies in a strange position.
“Most parents come home, and they’re still glued（胶水） to their phones, and they’re not listening to a word these kids are saying,” Ms. Zimmerman said.a anny in San Jose who works for familes that ban screen time. “Now I’m the nanny ripping out the cords from the PlayStations.”
