Julianna Margulies reveals in the May issue of W magazine that son Kieran Lindsay, now 2, was “a total surprise.”

“I was never much of a kid person,” she confesses. “I mean, I thought they were cute to look at but I didn’t want them in my house.”

Upon learning she was pregnant, however, Margulies says that she and husband Keith Lieberthal decided they were up for the challenge.

“I said, ‘Okay, I guess we’ll roll with it,'” the 43-year-old actress recalls.

Margulies’ enthusiasm for motherhood is matched only by her love for her part on CBS’s The Good Wife.

“I know this is going to sound corny, but I love my life,” she exclaims. “I love my baby, so I love getting to wake up with him. And I have the most amazing job.”

From the sound of things, each role makes her more appreciative of the other. After welcoming Kieran, Margulies says she felt “very overwhelmed” and found that she “needed to get back into someone else’s life.”

“I was like, ‘I’m a mother now; what is it I do for a living again?'” she recalls. “You lose your identity for a second when you have a baby. So even though I was in heaven [being a mom], it just felt so good to sort of go, ‘Oh, I can do this, too.'”

Happy to have relocated to her native New York, Margulies says there is no better place to raise her son.

“My family is here, my roots are here,” she notes. “I love sharing my kid with my family because I know no one else is going to care the way I do except them.”

“And babies have a way of making people live longer,” she adds.
