The book has an incredible wealth of information about the development of the brain and mind. Written by a neurobiologist and mother it provides lots of scientific background, yet still comprehensive. It focuses also on how much influence parenting can have and what stimulation can be helpful when.
The book is organized by the areas and capabilities that are developed. While this is good to learn about each and every aspect, it does not help when you want to get an understanding about all aspects for the current age of your baby.
