Closely observed and beautifully written, Oneness and Separateness is a classic study of the inner emotions and experiences of a child’s earliest life. Award-winning author Louise Kaplan explores the journey each baby makes from oneness with his mother to a “second birth” as a unique psychological being who begins to comprehend the difference between “I” and “you.” Using concrete examples, Dr. Kaplan takes parents through each phase of a baby’s life, and describes what the child is thinking and feeling, explaining the meaning behind universal childhood behavior, such as the first smile, the “peek-a-book” game, and temper tantrums.
