"This is a very practical and entertaining window into the baby's first year and a half. Vanderijt and Plooij have observed and found the vulnerable times in an infant's development that I independently came to in my book Touchpoints (Perseus). The authors' observations and practical suggestions are wonderful."

--T. Berry Brazelton, M.D., professor emeritus, Harvard Medical School

"Anyone who deals with infants and young children will want to read The Wonder Weeks. This book will open parents' eyes to aspects of their children's growth, development, changing behavior, and emotional responsiveness that they might otherwise not notice or find puzzling and distressing."

--Catherine Snow, Ph.D., Shattuck Professor of Education, Harvard Graduate School of Education
