This 4th edition has been entirely rewritten with the assistance of Dr. Robertson, who is also at the Toronto Hospital for Sick Children. It is primarily for the guidance of parents and has chapters on such topics as prenatal care, breast feeding, diet, development, illness and accidents. It is carefully, clearly written and up-to-date. There is a lot of practical material, such as lists of play things and suggestions for summer vacations. The recommendations for feeding schedules and diet are conservative compared to usual American customs.
