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 research. 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

Expensive app. I thought that I bought full version. New upgrade with payment plans to unlock content. All information in this app is available for free in other sources

Jeg har ikke en sjimpanse!

Denne appen er bare tull og tøys! Styr unna! Mesteparten av forskningen er gjort på sjimpanser og mannen bak (med sin kone) tjener masse på dette tøyset. Han mistet jobben som professor pga at dette er motbevist, og en annen forsker som motbeviste dette prøvde å publisere det. Da ville Plooji stanse dette. Resultatet er at han mista jobben. Så nå lever han på denne appen og boka hans.
