I'm a visual learner and the web site, Zero to Three, has an awesome feature that allows you to take a look inside your baby's brain as it develops.
Go to the Zero to Three web site: and select an age range from the pull-down menu. Depending on the age range you selected different hot spots on the brain will appear. Click on a hot spot to reveal questions to find out how a baby's brain develops during this period of brain growth. You'll also learn what you can do to enrich a very young child's development.
