Children need both latitude of expression and firmly enforced limits on their behaviors, in a blend that results in calm, patientmanagement. The key to success is to tailor the rearing environment to the developmental level of the child--what she or he can handle--and to individual differences among children.

Until the Second World War, it was unthinkable for a married woman of the working or middle class to disgrace her husband by working after marriage, because her employment indicated that he was a poor provider

Children are just different from one another, especially in temperament. Some are shy, others bold; some active, others quiet; some confident, others less so. Respect for individual differences is in my view the cornerstone of good parent-child relationships.

Given Freudian assumptions about the nature of children and the biological predestination of mothers, it is unthinkable for mothers voluntarily to leave their babies in others' care, without guilt about the baby's well-being and a sense of self-deprivation. Mothers need their babies for their own mental health, and babies need their mothers for their mental health--a reciprocal and symbiotic relationship.

Mothers have not always had the most important role in their children's upbringing, when they had other economic roles to play. Inpast centuries, fathers were the key parent in the upbringing of the next generation, because moral training, not emotional sensitivity, was thought to be central to successful child-rearing. Mothers were thought to corrupt their little ones with too much affection and not enough stern training.

Babies need social interactions with loving adults who talk with them, listen to their babblings, name objects for them, and give them opportunities to explore their worlds.

Ideas about mothers have swung historically with the roles of women. When women were needed to work the fields or shops, experts claimed that children didn't need them much. Mothers, who might be too soft and sentimental, could even be bad for children's character development. But when men left home during the Industrial Revolution to work elsewhere, women were "needed" at home. The cult of domesticity and motherhood became a virtue that kept women in their place.
