The socio-emotional development of young children has been a significant area of study for decades and early childhood is widely recognized not only as the period during which affective development originates but also as the phase in which the future course of life is set into motion. As life's pace and complexity continues to increase, expectations for children's abilities to control themselves and interact effectively with diverse individuals and groups continue to grow. This, the first volume in a series of edited books designed to synthesize research, theory, and practice, will focus on key interpersonal relationships affecting the young child. A distinguished group of authors will examine a wide array of relationships that affect the child today and influence the adult tomorrow-important bonds such as those between caregivers and infants; among siblings; between literate adults and the language-learning child; between the homeless and those providing support services, between principals and young students; and between recently immigrated preschoolers, teachers, and families, to name a few.
