Early childhood care and education has become a subject of increasing public interest in a great number of countries and among several international organizations and foundations. This book focuses on key issues in early childhood care and education, adding pedagogical, historical, and sociological perspectives to a body of research in education that has neglected important questions to date. The studies presented focus on effects of early childhood care and education on children, on the importance of family background for child development, on the use of institutional services among different families, on the history of such services in France and in the United States of America, and on the way in which children acquire competences both in early childhood care and education institutions and in a family context.
