Look for opportunities to separate your daughter from technology for extended stretches of time. Demanding jobs, summer camps, and family trips can require—or inspire—long breaks from digital technology. Teenagers can be more willing to go along with no-tech trips if they are allowed to catch up with the digital world at preplanned times. While away from home, some families develop a rule that everyone is allowed to check his or her phone and computer for a half hour each morning and evening but otherwise agree to go off the grid.
