Both Kim and Kylie admit sister Khloe was "so freaked" inside the delivery room with Jenner.
The two sat down for a Q&A session for Evening Standard magazine, where they tackled everything from how Kylie and Travis Scott came up with the name Stormi, to why Khloe Kardashian was "freaked" in the delivery room, to her current thoughts on plastic surgery.
The Story Behind Stormi's Name
"I really don't know how we thought of Stormi. Her dad insisted it was him, but I feel like it was me," Kylie said of her newborn baby girl. "And that kind of just stuck with us. And then I didn't really like just Storm -- I didn't feel like that was her name. So then it became Stormi. And it just stuck. I feel like there were a lot of other names that I might have even liked better, to be honest, but I feel like Stormi picked her own name, like it was just her name."
Fun fact: According to her birth certificate, Stormi doesn't have a middle name.
On Life After Giving Birth
"I feel like it's just been so amazing and so much fun," the 20-year-old said of motherhood. "I'm learning so much more about myself and life, and it's been such a great experience. Of course there's hard times and stuff...even in the beginning, just not sleeping, the nights, like, baby blues...and all the ups and downs. And also, even when I'm here, it was so hard to leave this morning. I'm like, 'I'll be right back! I'm so sorry, I have to leave!' and she doesn't even know what's going on. I think about her all the time, anywhere I am. I would rather be with her or wish she can come everywhere."
"Everyone says you change completely when you become a mom, but I really feel the same, just better," she continued. "So I don't know what really has completely changed my world, besides her, of course. But I feel like it's only gotten better. You're less selfish -- and I actually enjoy changing diapers. It's really satisfying. To make her clean again. And I don't know, the whole thing is really...it's like such an amazing experience."
Her Thoughts on Plastic Surgery
Though Kylie has been very open about getting work done on her lips in the past, she's not currently on the hunt for any cosmetic upgrades.
"I feel like if it makes you feel better, and if that's what you want to do, I'm not against it," she said when Kim asked her about going under the knife. "Right now, I probably wouldn't do anything, actually."
Kim responded by adding, "You're 20, so I hope not! We'll talk in 20 years, and then maybe you'll have a different answer."
The Best & Worst Things About Being on a Reality Show
Kylie's been on reality TV since 2007, before she was even a teenager. Despite all the attention that comes with "Keeping Up With the Kardashians," she called it "the best job anyone could ever ask for" because she gets to "hang out with [her] family all day."
"I think we spend so much more time together," Kylie said. "The worst thing is maybe the moment when you shoot super personal things, and probably, like, right before it comes out, and you're letting people into your life. But then it always ends up so positive because there's so many people going through the same things as us. So it's like so relatable for them. And I think that's what we've learned over time."
When asked if Stormi will ever appear on reality TV, Kylie said, "I have thought about it, but I haven't come to a conclusion yet."
How Khloe Helped In the Delivery Room
Kim said that Khloe was "so freaked" while in the delivery room with Kylie, and told her, "Hey, you guys, never should a pregnant woman be in another delivery room until it's your time.'"
"I agree with that," Kylie said. "No, but I really needed her. I needed Khloe in the room with me. I think it made her more scared. She was there for all my other sisters. She's just very, very nurturing, so she really helped me through the whole thing. Everyone should have Khloe in their delivery room."
Other Random Tidbits
Kylie kept it predictable when asked to name her favorite designer and musician. For the first, she said Kim's husband, Kanye West, because he "has an advanced way of thinking, and everything he makes is just innovative and cool." For musician, it was her baby daddy. "I really love everything about [his music] -- the way it makes you feel."
Kylie also said the one thing nobody knows about her is that she has four dogs. And when asked to reveal what the last text message she sent said, she replied, "I think I told my security to get me apples and peanut butter!"
