Punishment is a tool designed to make a child "pay for what they did" and to feel bad about the way they acted. The belief is that the bad feeling will stick with them and motivate them to not repeat the behavior or action. But punishment has side effects that can create more problems for the parent then they originally had. For example, making a child feel bad can backfire and motivate them to hide and lie about their mistakes. It can also damage the parent/child relationship. Think back to your own childhood and remember a time when you were punished. How did you feel? How did you feel about yourself at that moment? What did you want to do as a result of the punishment? How did you feel toward the punisher? I've asked these questions numerous times in my workshops and not once did any adult say they felt good about anything in that moment. We now know that making a child feel bad about what they did affects the way they think and feel about them self.
