For use in conjunction with training videotapes illustrating key concepts and caregiving techniques, this guide aims to help caregivers set up environments for infants and toddlers that promote young children's health, safety, and comfort, meet their developmental needs, and provide caregivers a comfortable and convenient place to work. Section 1 identifies and describes eight key concepts that need to be considered when designing any child care environment: safety, health, comfort, convenience, child size, flexibility, movement, and choice. In addition to defining each concept, the section suggests practical steps that caregivers can take to improve certain features of the environment. Section 2 considers those aspects of the environment that make each setting unique and suggests how to work with that uniqueness in environmental planning. The section provides a framework for looking at particular caregiving environments. Rich in illustrations and devoted to practical concerns, Section 3 explores specific areas in the child care environment, including the entrance and parent communication area, learning and development centers, peer play areas, multilevel areas, rest and sleeping areas, toileting, washing up, feeding, and food preparation areas, storage and shelves, and outdoor space. The guide closes with practical tips, suggested resources, and a glossary of environmental terms. (RH)
