HALF a century ago, the conventional wisdom was that having a child was the surest way to build a happy marriage. Women's magazines of that era promised that almost any marital problem could be resolved by embarking on parenthood. Once a child arrives, "we don't worry about this couple any more," an editor at Better Homes and Gardens enthused in 1944. "There are three in that family now. ... Perhaps there is not much more needed in a recipe for happiness."
Over the past two decades, however, many researchers have concluded that three's a crowd when it comes to marital satisfaction. More than 25 separate studies have established that marital quality drops, often quite steeply, after the transition to parenthood. And forget the "empty nest" syndrome: when the children leave home, couples report an increase in marital happiness.
But does the arrival of children doom couples to a less satisfying marriage? Not necessarily. Two researchers at the University of California at Berkeley, Philip and Carolyn Cowan, report in a forthcoming briefing paper for the Council on Contemporary Families that most studies finding a large drop in marital quality after childbirth do not consider the very different routes that couples travel toward parenthood.
Some couples plan the conception and discuss how they want to conduct their relationship after the baby is born. Others disagree about whether or when to conceive, with one partner giving in for the sake of the relationship. And sometimes, both partners are ambivalent.
The Cowans found that the average drop in marital satisfaction was almost entirely accounted for by the couples who slid into being parents, disagreed over it or were ambivalent about it. Couples who planned or equally welcomed the conception were likely to maintain or even increase their marital satisfaction after the child was born.
Marital quality also tends to decline when parents backslide into more traditional gender roles. Once a child arrives, lack of paid parental leave often leads the wife to quit her job and the husband to work more. This produces discontent on both sides. The wife resents her husband's lack of involvement in child care and housework. The husband resents his wife's ingratitude for the long hours he works to support the family.
When the Cowans designed programs to help couples resolve these differences, they had fewer conflicts and higher marital quality. And the children did better socially and academically because their parents were happier.
But keeping a marriage vibrant is a never-ending job. Deciding together to have a child and sharing in child-rearing do not immunize a marriage. Indeed, collaborative couples can face other problems. They often embark on such an intense style of parenting that they end up paying less attention to each other.
Parents today spend much more time with their children than they did 40 years ago. The sociologists Suzanne Bianchi, John Robinson and Melissa Milkie report that married mothers in 2000 spent 20 percent more time with their children than in 1965. Married fathers spent more than twice as much time.
A study by John Sandberg and Sandra Hofferth at the University of Michigan showed that by 1997 children in two-parent families were getting six more hours a week with Mom and four more hours with Dad than in 1981. And these increases occurred even as more mothers entered the labor force.
Couples found some of these extra hours by cutting back on time spent in activities where children were not present — when they were alone as a couple, visiting with friends and kin, or involved in clubs. But in the long run, shortchanging such adult-oriented activities for the sake of the children is not good for a marriage. Indeed, the researcher Ellen Galinsky has found that most children don't want to spend as much time with their parents as parents assume; they just want their parents to be more relaxed when they are together.
Couples need time alone to renew their relationship. They also need to sustain supportive networks of friends and family. Couples who don't, investing too much in their children and not enough in their marriage, may find that when the demands of child-rearing cease to organize their lives, they cannot recover the relationship that made them want to have children together in the first place.
As the psychologist Joshua Coleman suggests, the airline warning to put on your own oxygen mask before you place one on your child also holds true for marriage.
