In Daniel Gilbert’s 2006 book "Stumbling(跌撞) on Happiness," the Harvard professor of psychology looks at several studies and concludes that marital(婚姻的) satisfaction decreases after the birth of the first child and increases only when the last child has left home. He also declares that parents are happier grocery shopping and even sleeping than spending time with their kids.
The most recent comprehensive study on the emotional state of those with kids shows us that the term "bundle of joy" may not be the most accurate way to describe our kids. "Parents experience lower levels of emotional well-being, less frequent positive emotions and more frequent negative emotions than their childless peers," says Florida State University’s Robin Simon, a sociology professor.
Simon received plenty of hate mail in response to her research,which isn’t surprising. Her findings shake the very foundation of what we’ve been raised to believe is true. In a recent NEWSWEEK Poll, 50 percent of Americans said that adding new children to the family tends to increase happiness levels. But which parent is willing to admit that the greatest gift life has to offer has in fact made his or her life less enjoyable?
Is it possible that American parents have always been this disillusioned(有幻觉的)? In pre-industrial America, parents certainly loved their children, but their kids also served a purpose—to work the farm, contribute to the household. Today, we have kids more for emotional reasons, but an increasingly complicated work and social environment has made finding satisfaction far more difficult. Raising children has not only become more complicated, it has become more expensive as well. The National Marriage Project’s 2006 report says that parents have significantly lower marital satisfaction than nonparents because they experienced more single and child-free years than previous generations.
As for those of us with kids, all the news isn’t bad. Parents still report feeling a greater sense of purpose and meaning in their lives than those who’ve never had kids. And there are other rewarding aspects of parenting that are impossible to quantify.
