Kids can drive you crazy. With worry. With anger. With fear. With love. But a little insanity also brings a whole lot of happiness, USA Today reports.

According to the newspaper, two recent studies have found that past research concluding that childless adults are happier than parents is “flawed”—and that the opposite is actually true for today’s moms and dads.

“We find no evidence that parental well-being decreases after a child is born to levels preceding the children, but we find strong evidence that well-being is elevated when people are planning and waiting for the child and in the year when the child is born,” says Mikko Myrskylä, a coauthor of one of the recent studies, according to USA Today.

In the other recent study, coauthor Chris Herbst found “parents have become relatively happier than non-parents over the past few decades,” the newspaper reports.

But having more kids doesn’t necessarily make you happier, Rachel Margolis, Myrskylä’s coauthor, tells USA Today.

“The first child increases happiness quite a lot,” she tells the newspaper. “The second child a little. The third not at all.”

Well, no kidding. Anyone with three kids knows you’re too exhausted to feel anything but tired.
