Parents may choose to use physical punishment (such as spanking) to stop undesirable behavior. The biggest drawback to this method is that although the punishment stops the bad behavior for a while, it doesn’t teach your child to change his or her behavior. Disciplining your child is really just teaching him or her to choose good behaviors. If your child doesn’t know a good behavior, he or she is likely to return to the bad behavior. Physical punishment becomes less effective with time and can cause the child to behave aggressively. It can also be carried too far into child abuse. Other methods of punishment are preferred and should be used whenever possible.
