The Wonder Years by Tanya Remer Altmann (MD, Fellow AAP) is a fantastic book. Here are the names of the chapters:
-Movement
-Fine Motor Development
-Sensory Development
-Mental Development
-Social and Emotional Development
-Bowel and Bladder Development
-Developmental Concerns
-Factors Affecting Development
In each section, there is an 'approximate timing of events' and a 'parental participation'. I absolutely love how it gives parents ideas on age-appropriate activities and games to help them with developmentally appropriate activities. I'm a first time mom and this is all 'new' to me, so I wanted to get an idea from someone who works with tons and tons of children as my experience is very narrow and limited. I have found the book to be such a wonderful help, especially the 'parental participation' area.
