Experts Reviews

This is a very practical and entertaining window into the baby’s first year and a half. van de Rijt 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.

Anyone who deals with infants and young children will want to read ‘The Wonder Weeks.’ ‘The Wonder Weeks’ 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.
