This early work on child development is both expensive and hard to find in its first edition. It contains details on normal and abnormal development along with treatment methods. This is a fascinating work and is thoroughly recommended for anyone with an interest in the history of child development. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
