In this approach to the manifold problems of 20th century parents, Dr. Dreikurs has wisely stressed the constructive aspects of the parental role in child rearing, offering many concrete suggestions for positive action in specific settings. His discussion of mental hygiene principles is couched in language which has meaning to the interested parent, and his treatment of such potentially difficult areas as the setting of limits for aggressive behavior, the sensitive enlightenment of the child on sexual matters, and the handling of minor behavioral deviations by the judicial usage of matter-of-fact and superficial interpretations of the child's partially conscious goals of behavior seem sound and effectively developed.
