The Building Blocks program uses six picture books to show preschoolers the kinds of skills and behaviors they should be developing now that will protect them from alcohol and drug use later. This Building Blocks guide for parents of children working with the program at their child care center gives information and activities to work with children at home to help them build: (1) self-concept and self-confidence; (2) a sense of personal responsibility; (3) trust in self and others; (4) an understanding of the difference between fantasy and reality; and (5) the ability to solve problems. The guide summarizes the picture books used in the program and suggests activities to do at home. Also included are a description of the parents' role in rearing a drug-free child, answers to questions parents often ask about alcohol and other drugs, and sources of information on alcohol and other drug abuse prevention.
