Life requires that certain things be accomplished in a timely fashion.
Children must get up, get dressed, eat, take care of basic grooming, take care of responsibilities, and participate in the chores of family living. If getting kids to do what must be done becomes a struggle, family life becomes a major hassle. I believe that a major goal or parenting is to gain the child's cooperation. Ultimately, the child must tell himself what to do. I also believe that children need to know that they must do what is required.
