Child care is an invisible part of the economy.

There is nothing intrinsically better about a child who happily bounces off to school the first day and a child who is wary, watchful, and takes a longer time to separate from his parents and join the group. Neither one nor the other is smarter, better adjusted, or destined for a better life.

It gives us more flexibility, so we can do more, but it also creates the expectation of the instant response. It can take away your sense of control over your time.

Cultural expectations shade and color the images that parents-to-be form. The baby product ads, showing a woman serenely holding her child, looking blissfully and mysteriously contented, or the television parents, wisely and humorously solving problems, influence parents-to-be.

In a study that I just did, I found that it was older children, not younger children, who felt that they didn't have enough time with their parents.

Parenthood brings profound pleasure and satisfactions--the unparalleled pleasure of caring so intensely for another human being, of watching growth, of reliving childhood, of seeing oneself in a new perspective, and of understanding more about life.

In families children tend to take on stock roles, as if there were hats hung up in some secret place, visible only to the children. Each succeeding child selects a hat and takes on that role: the good child, the black sheep, the clown, and so forth.
