Abstract
Nurses, therapists and teachers of the preschool‐age special child can use knowledge of normal child development to increase their understanding and effectiveness in working with special children. Five important aspects of knowledge are: theoretical principles about how all children grow and learn; normative child development milestones; research findings on caregiver‐child interactions that optimize developmental outcomes; programmatic research findings on enrichment curricula for children at risk for socio‐cultural retardation; and communication techniques and programs to enhance pro‐social behaviors of children in families and in group‐care situations.
