A few years ago a friend suggested that I try the "no-nag technique." According to this technique, you simply tell your child to do something one time, and when they don't do it, you enforce a consequence. You do not tell them to do something over and over again. You do not try to control your child's behavior by threatening their lives if they don't do it. You simply say it once, walk away, and then enforce a consequence if they disobey.
