Building Blocks is a series of six picture books for preschoolers designed to help caregivers and preschool teachers lay the foundation for alcohol and other drug use prevention among children in their care. The books focus on those behaviors and life skills that help children grow up to be drug free, namely: positive self-concept and self-confidence; a sense of personal responsibility and responsibility to others; trust in self and trust in others; the ability to distinguish between fantasy and reality; the development of the capacities needed to understand cause and effect and to apply that understanding to solving problems. This Building Blocks guide for caregivers offers suggestions for using each picture book; the guide includes ideas for involving parents, basic information about risk factors for alcohol and other drug use, a list of resources available for further information about alcohol and other drug use, and a list of other story books to share with the children in the program.
