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.

It is important for practical and psychological reasons to call any reasonably stable group that rears children a family.... The advantage of this view is that traditional and nontraditional families can all be seen to serve the interests of children. Children can also feel comfortable with an approved family form, even if it is not traditional.

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.

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.

The time-use studies also show that employed women spend as much time as nonworking women in direct interactions with their children. Employed mothers spend as much time as those at home reading to and playing with their young children, although they do not, of course, spend as much time simply in the same room or house with the children.

All we know is that the school achievement, IQ test score, and emotional and social development of working mothers' children are every bit as good as that of children whose mothers do not work.

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.
