Soldiers returning home from World War II were usually eager to go on with their lives. For most, that meant starting a family. Between 1946 and 1960, 63 million babies were born in the United States, up 22 million from the fifteen-year period before that. this big jump in the birth rate came to be known as the baby boom (婴儿潮). Before the war, American children were raised very strictly. They were often told to be "seen and not heard." After the war, however, young parents raised their children according to different ideas. Dr. Benjamin Spock's Common Sense Book of Baby and Child Care, published in 1946, emphasized flexibility (灵活性) in raising children. Spock encouraged parents to listen to their children and respond to their wishes. New parents quickly made Dr. Spock's book the best-selling book in US history. By 1952, sales had reached 4 million copies per year for the next eighteen years. Critics (批评家) who believed that the old ways of raising children were best accused Spock of being too permissive. They thought his ideas would spoil children.

But Spock opposed strict discipline because he thought there were was "no such thing as a bad boy." By this he meant that, although a child's behavior. may be bad, the child is not. Millions of baby-boom parents were influenced by Spock's advice, which brought a revolution in the way children were raised.
