One of a series written for child caregivers working in military day care centers, this book is about creating environments for "pretoddlers," children 13 through 24 months of age. The book is divided into two parts, with selected resources at the end. Part 1 discusses some ways to organize and arrange physical space for pretoddlers, providing several checklists for assessing center environments. Part 2 suggests ways to use people and materials in the center space. Managing the center environment for pretoddlers' development, encouraging development through play, using materials creatively, and finding resources are among the topics discussed. Checklists related to each of these topics are provided along with a brief annotated bibliography of related books and records. (RH)
