Book excerpt: The teasing, squabbling, competition, and ferocious fights of brothers and sisters can drive any parent to frantic desperation. At the same time, Drs. Brazelton and Sparrow point out, siblings are learning from one another and deep, close relationships are forming that will last a lifetime. In this absolutely indispensable addition to the Brazelton Way series, the authors show how parents can defuse much of the bickering, while helping to strengthen warm relationships. They help parents understand the universal “Touchpoints” of sibling rivalry at each age, as well as the problems in particular family situations. From the combined delight and resentment that a sibling feels toward a new baby, to birth order, blended families, sex play, scapegoats, meltdowns, and competition in school, parents will find welcome advice in this wise, comforting book.
