Presenting both a theoretical foundation and proven strategies for helping caregivers become more attuned and responsive to their young children’s emotional needs (ages 0–5), this is the first comprehensive presentation of the Circle of Security (COS) intervention. The book lucidly explains the conceptual underpinnings of COS and demonstrates the innovative attachment-based assessment and intervention strategies in rich clinical detail, including three chapter-length case examples. Reproducible forms and handouts can be downloaded and printed in a convenient 8 1/2” x 11” size. COS is an effective research-based program that has been implemented throughout the world with children and parents experiencing attachment difficulties.

“The summary of attachment theory presented through this new framework is insightful and accessible. The discussion of the intervention itself and case studies make this book a must read…. Highly recommended. Upper-division undergraduates through faculty and professionals: general readers.” —Choice Reviews

“Brilliant, creative, and transformative are words that don’t fully capture the true power of this approach. The authors have woven attachment theory into a research-based, innovative intervention that helps infants and their parents move toward security and a life of resilience and well-being. Soak in the wisdom of these masters and you’ll be forever grateful—I certainly am. The book provides an intricate yet practical therapeutic exploration infused with the dedication and insights of its authors.” —Daniel J. Siegel, MD, Department of Psychiatry, UCLA School of Medicine; author of Brainstorm: The Power and Purpose of the Teenage Brain.
