This Second Edition of the Handbook does much more than update the first edition; because the field of infancy has grown so much in recent years, and continues to grow, this volume now includes perspectives on many new issues. Covers issues such as the concept and influence of temperament, meaning of attachment relationships, continuities and discontinuities, infant mental health, media, society and child development. The Second Edition includes several European chapters, providing a review of infancy research from the Continent. Includes more clinical perspectives on infant development and discusses implications of the research for intervention and application.
