There's old-fashioned good sense, tender loving care, a smattering of Piaget, Pavlov, and Skinner in this home guide to better baby development in the first year of life. The author has been working with infants and children for almost 50 years, the last 25 at the Institute for the Care of Mother and Child in Prague. His program is for a graded series of exercises to develop a baby's mental and physical muscles. Some of these are intuitively obvious to seasoned parents (like lying down and letting a baby surmount soft flesh in early crawling, or responding to a child's mumblings with similar but more meaningful sounds), Doctor Koch assures that daily practice of his program will foster more rapid development--walking or talking earlier, for example. But he insists this is not the point. The real concern is getting a child off to the best possible start at the time he is most vulnerable and impressionable. Along with the exercises there are suggestions for the kind of toy to build or employ, the kind of learning that can be encouraged at feeding times or in games, and so on. Fortunately, most of the more complicated exercises (for the parent in holding the child, not for the child) are illustrated. If the book is taken in the spirit in which it is written--as a dynamic and flexible program for the mutual benefit of parents and child--and not a rigid schedule to promote baby's success, it will be a fine and practical addition to the baby lore shelf.
