What makes children happy? Stuff. That’s what most parents think, it seems. Xbox 360, Furby, Lil Swanky clothing, M&M’s and licorice ropes, Lego sets—whatever little Madison and Brayden desire.

If Mom and Dad took a break from indulging their kids’ whims and thought about it, they might admit that it’s not working. You don’t have to peek down too many aisles in the toy store to see children who already have everything—and are miserable brats. There must be another way.

Now, science is supplying some evidence to teach us what was once common knowledge: that it actually is more blessed to give than to receive.

In their recent study “Giving Leads to Happiness in Young Children,” psychologists at the University of British Columbia found that giving puts smiles on young children more than getting. “[B]efore the age of 2, toddlers exhibit greater happiness when giving treats to others than receiving treats themselves,” they wrote. “Further, children are happier after engaging in costly giving—forfeiting their own resources—than when giving the same treat at no cost.”

cnn summed up the findings: “These studies confirm some age-old wisdom about happiness: If the goal really is to make our children happy, perhaps what we ought to be doing is not overindulging them, but giving them the opportunity to give” (Sept. 17, 2012).

The study’s lead author, Lara Aknin, insists that children receiving pleasure from giving away their goldfish crackers shows the emotional rewards we can all enjoy from personal sacrifice. “You can construe that pro-social behavior broadly to include giving time volunteering, giving money to causes or giving other resources,” she told cnn. “All of these correlate to happiness.”

Other studies have confirmed that this life law doesn’t just apply to kiddos with crackers. For example, research has shown that teens are happier when they’re giving. “Adolescents who identify their primary motive as helping others are three times happier than those who lack such altruistic motivation,” says Christine Carter, a sociologist at the University of California. Teens who are givers are not only happier, but are more excited about life, and more involved at school and in their families. Carter says, “Generous behavior reduces adolescent depression and suicide risk, and several studies have shown that teenagers who volunteer are less likely to fail a subject in school, get pregnant or abuse substances.”

And it doesn’t change when we become adults, as a multitude of research bears out. Whether a person donates money to charity, volunteers time or commits random acts of kindness—like providing directions to a lost traveler or holding the door for someone—reports show he will be happier and suffer less anxiety and depression.

In 2000, the Social Capital Community Benchmark Survey found that of 30,000 American households, those who gave money to charity were 43 percent likelier to say they were “very happy” about their lives compared to non-givers. Those who volunteered time were 42 percent likelier to be very happy than those who didn’t.

Ergo, a surefire way to lead your child to a happier life, both now and on into adulthood, is to teach him to give. But how?

We all know that money can’t buy happiness, but so many of us still make the mistake of trying to purchase it for our children. Wise up and flip the script. Help your child experience all the benefits of the happy way of life—the way of give.
