First photos of Kourtney Kardashian with newborn son Mason

Forget about keeping up with the Kardashians.

Now, it's Kourtney Kardashian who's trying to keep up with her newborn son Mason.

In an interview with "Life & Style," Kardashian, 30, and Mason's father Scott Disick, 26, gush over the new addition to their family.

"It feels amazing. It's just so indescribable. You don't get how good being a parent feels until it happens to you," Kardashian tells the magazine.

Desick is no less effusive in the issue of "Life & Style" out now.

"My first time holding him was definitely special. But holding him the second time was even more special, and the third time was even more special than that," he told the magazine. "I fall so much more in love with this kid every day. I can't imagine how much more in love with him I'm going to be by the time he's 5 or 10 or 20!"

In typical form, Kourtney says the Kardashian girls broke all the rules when it came to the labor.

"You're only allowed to have two people in the room because of the swine flu," Kourtney says, "so we snuck Kim and Khloé in!"

Now that she's a mother, Kardashian is also enjoying a new type of nightlife.

"We're on Mason's schedule," she says, "waking up every couple of hours to breastfeed. But it's fun to get up and see him. I miss him by the time I see him again."

According to Kourtney, the delivery was "surprisingly easy," so easy, in fact, she's already thinking of round two.

"Kim and I are 18 months apart," she says. "Growing up, we did everything together. It would be nice for Mason to have a little brother or sister that many months apart too."
