Almost a year ago, when my daughter turned 12, she received an old iPhone for her birthday. She wanted to start babysitting, so a phone would be helpful. And most of the kids in her grade had phones already, so that pressure lingered too. I was a little nervous about the effect the phone would have on her. I’ve seen many kids turn into phone zombies and disconnect from their families. So I did some research to put some family device norms in place.
