Make rules and stick to them.
Rather than giving your teen more freedom just because he’s older, it may be good to have your teen show he’s responsible enough for his freedom. You can do that by making rules and sticking to them. Don’t make rules up on the spot. Discuss rules ahead of time with your teen so he clearly understands them. “Your curfew is 10:00 on Friday night. If you’re going to be any later than that, send me a text message. If that doesn’t happen, you won’t be able to play video games for a week.” Then stick to it.
