The reality TV star is set to have her first child with rapper Kanye West in July, and will choose to find out whether it is a boy or a girl if it is revealed on a scan.
She told E! news: "I don't know what we're having yet. I do want to find out, I do."
The 32-year-old star would not say whether she prefers to have a boy or a girl, but added so far her growing bump has not interrupted her sleep patterns at all.
She explained: "I sleep amazing, it's like the best sleep ever. I'm a really easy sleeper though, you can put me on the couch with all these people in the room and say, 'You've got 10 minutes,' and I'll take an eight-minute nap."
Kris trying not to "gush"
Kim added her pregnancy is going so smoothly, she doesn't "feel anything, and I don't crave anything".
The star's mother, Kris Jenner, is preparing for the baby, but also biting her tongue and trying not to "gush" too much to Kim about it.
"I think Kim's probably so sick of my advice by now, but what it does for me is it brings back memories from when I was pregnant with them," Kris revealed.
"So she'll say something and I'll think, 'Oh my gosh, I remember back then,' and I'll try to share that. And, you know, I try not to gush too much because I can be annoying, I'm sure."
