Scott Disick opened up about his new son, Reign Aston, a few days after reports got out that he vacationed in Aspen just a few weeks after the baby boy's birth.

"It's my third time so it's kind of a charm," the 31-year-old reality TV star said according to Us Weekly. "I think I kind of know it by now. The first one was scary. The second was less scary. The third one was, okay -- I got a whole team over here."

Disick added his longtime girlfriend Kourtney Kardashian has loved giving birth each time and is practically in heaven after welcoming their new baby boy.

According to Disick, his two older children, 5-year-old Mason and 2-year-old Penelope, are handling the new bundle of joy quite well.

"I really would have thought the other two would have been jealous," he said. "They're so accommodating and welcoming. I don't think I would have been that way if I had a sibling. I cannot get over how much affection the other two have shown the baby. It's like -- thank God, knock on wood."

Yet, Disick still does not know how to describe what fatherhood means to him.

"It's so hard -- it's like how do you sum up someone who's gonna carry on your name and life and see them grow every day? I wouldn't be able to wrap it up into one word," he explained. "It's pretty wild to see something that you made turn into a human being that you are today. It's scary too -- but cool."

Meanwhile, Kardashian, a mother of three, recently revealed that this last pregnancy has been tougher on her than the first two, Fashion and Style reported.

The "Keeping Up With the Kardashians" star posted a picture to her Instagram page of baby Reign and his sister Penelope, on Friday, but it does not show Reign's face.

"Brothers and sisters," the caption says.
