This small pamphlet is packed full of sound principles about child development and behavior, and gives many clues to the better management of the so-called behavior problems that beset parents, teachers and pediatricians so overwhelmingly today. Although it was written for parents and teachers primarily, this material may serve the pediatrician as well, as a primer on child psychology. The authors present their material briefly, in simple English with apt illustrations. The construction of the paragraphs facilitates further ease of reading and grasp of information.
