First of all, it is a book about the Dionne quintuplets. It is a poor title, since it does not capitalize the main sales appeal, and a poor sub-title, since it is a reportorial job rather than a psychological one. Description of their nursery -- hospital, findings on their development, graphs of height, weight, illnesses, motor and language progress, adaptive behaviour, etc. Who is who -- are they identical? Their habits, various types of play activities, equipment, daily programs, eating, sleeping and toilet habits. Discipline, in the modern progressive line. Emotional adjustment, preferences, fear and anger responses. It sounds technical but it is not, and there is a good deal of anecdotal material. A popular subject and Blatz is a good man.
