Discipline is not what you do to the child, but what you do with and for the child. Punishment in a positive sense goes back to the fact that, regardless of what we do, some of our discipline techniques are not going to be successful, or indeed the child may still misbehave or behave in a manner in which we need to correct that behavior rather than to guide it. For our purposes then, positive punishment means to correct behavior that you do not want repeated or that you see as inappropriate for the situation. Helping children correct behavior is taking the time to give feedback about the choices they made and discussing why their choices are important so they can make a wiser choice next time. Use reasonable consequences.
Consequences can occur naturally, or they can be structured.
An example of a structured consequence is denying television until the toys are put away. An example of a natural consequence is, instead of nagging a child to finish lunch, remove the uneaten food and don't allow more until afternoon snack time. The natural result of not finishing lunch is hunger pains an hour later. The child's own inner discomfort is much more effective than your nagging the child to finish lunch. Remember that consequences should be directly related to the misbehavior.
