THE HAPPIEST TODDLER ON THE BLOCK: The New Way to Stop the Daily Battle of Wills and Raise a Secure and Well-Behaved One- to Four-Year-Old

California-based pediatrician Karp offers a unique approach to the tantrums, melt-downs and overriding challenges that often accompany the demanding years from one to four. Viewing toddlers as primitive thinkers akin to prehistoric man, Karp divides his patients into developmental groups: the "Charming Chimp-Child" (12 to 18 months), the "Knee-High Neanderthal" (18 to 24 months), the "Clever Cave-Kid" (24 to 36 months) and the "Versatile Villager" (36 to 48 months). Parents may find the toddler years so frustrating, Karp suggests, because they don't speak their child's language. To deal effectively with the undeveloped brains of toddlers, one must understand "Toddler-ese," he says, a method of talking to youngsters that employs short phrases, repetition, a dramatic tone of voice and the use of body language. Although the author admits parents may feel foolish speaking in this manner, he nevertheless maintains that the approach soothes children by respecting their needs. Additionally, Karp offers suggestions for positive discipline (e.g., loss of privileges and time out) and guides parents through early expected milestones, while acknowledging that a child's individual temperament (e.g., easy, cautious, spirited) will uniquely influence the pace of his or her development. While some readers may find the relentless cave-kid metaphors irksome, Karp's gentle, easygoing tone is soothing and offers new hope and strategies to those who may have given up on making sense of the toddler years.
