Parents sometimes think of newborns as helpless creatures, but in fact parents' behavior is much more under the infant's control than the reverse. Does he come running when you cry?

The best way of thinking of an attachment in my view, is to see it as the outcome of an interaction between two people, each of whom contributes to the quality of the relationship. Most parents can promote a secure relationship with a calm, pleasant, patient baby. Only particularly sensitive and patient parents can promote a secure attachment to a difficult baby.

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.

Children thrive in a variety of family forms; they develop normally with single parents, with unmarried parents, with multiple caretakers in a communal setting, and with traditional two-parent families. What children require is loving and attentive adults, not a particular family type.

Fortunately for common sense, psychological research has shown that babies with more than one attachment are less distressed whenmother leaves to go to work. They are more content and playful in the presence of other adults, meaning that they feel secure with people other than Mother.

Each era invents its own child. Over the past 500 years, conceptions of the child changed gradually from an ill-formed adult who must be subjugated to society's goals to a precious being who must be protected from unreasonable social demands. Childhood has come to be seen as a special period of life, rather than as a temporary state of no lasting importance for adulthood.

Parents ought to feel more comfortable about the care of their children than some experts would seem to permit. If children were so fragile and parenting so difficult to learn, where would we all be as adults?
