Think of it as a portable, at-a-glance version of the calendar leap chart in The Wonder Weeks. Where the book describes in-depth and easy-to-understand terms the incredible developmental changes your baby goes through, the app is the perfect leap calendar companion to track your baby’s mental development (during the first 20 months).
By knowing what is going on inside the head of your baby, you can help him to make the leap more easily and stimulate his development.

The Wonder Weeks app helps new parents by:

- Calendar Showing when your baby makes a leap in his mental development

- What your baby can understand & learn after this mental leap

- What your baby can do after this leap

- What you can do to help your baby

This app is also a handy reminder for new parents when their baby’s brain is changing, or “leaping,” the baby is making a significant advance in mental development, and with each step forward comes a drastic change in the way your baby sees the world around him. Because these leaps come so quickly, the “new world” and new abilities can sometimes be scary, and the development can initially manifest in poor sleep, bad appetite, crying, clinging and crankiness – exhausting and frustrating mom and dad.

International experts on The Wonder Weeks:
 “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 Books Group). 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
