This sequel to The First Twelve Months of Life (1973) offers similarly broadbased descriptions of a child's second year in the same reassuring tone. After characterizing overall patterns of motor and language development and the acquisition of social skills, the Caplans provide a month-by-month accounting, not a rigid timetable but corn men growth sequences based on research at The Princeton Center for Infancy and Early Childhood. They outline an increasingly complex emotional repertoire, the movement toward autonomy, the significance of egotistical behavior, and a tendency for intentions to outrun abilities. In addition to citing authorities such as Erikson, Piaget, Ginott, and Bloom, they indicate ""critical periods""--when intervention is salutary--and consistently show an awareness of everyday happenings: why the pot cabinet is such a treausre chest, when to play with outbursts of ""no,"" how rituals can go from innocuous to unmanageable. Accessible format, fine bibliography--a best buy for parents.
