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.

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.

We know that babies develop as well in nonmaternal as in maternal care, as long as the care is of good quality. The issue is not who gives the care but the quality of that care,... The guilt trip is, in my view, a hangover of another era and of unacknowledged tactics to keep women in their proper place--at home full-time.

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.

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.
