This book outlines major characteristics for each of the developmental domains in a concise, non-techinical, point-by-point format. Developmental profiles have been expanded to now include middle childhood. Sections highlighting children's daily routines and patterns have been incorporated to assist readers in understanding the nature of development and translate emerging skills into everyday behavior. Updated information about prenatal care and brain research has been added and critical safety considerations for each developmental stage with suggestions for appropriate adult supervision are identified. Supporting the importance of family, respect for diversity, and the uniqueness of individual differences in children's abilities from pre-birth to age twelve, this book places emphasis on the quality of care, learning experiences, and education for the wholesome development of all young children.
