One type does not work for all children, even children in the same family.
Unlike hand-me-down clothes, discipline must be tailored to the individual child.
Children of varying ages and stages of development must be dealt with accordingly.
Before you discipline
Children often get involved in things that they don't understand are wrong or dangerous. Deal with those types of infractions differently than you deal with incidents of willful disobedience.
