Kim Kardashian West has given some insight into how her children are named.

She and husband Kanye West are expecting their fourth child, a boy, who is set to be born via surrogate.

Kardashian West appeared Monday on “Jimmy Kimmel Live!” in Las Vegas with her sisters Kourtney and Khloe Kardashian.

The TV reality star-turned-mogul said that when it comes to baby names, “We all weigh in.”

“I definitely take a family survey, but it’s usually after the baby’s born and we’re trying to figure out what the baby looks like,” Kardashian West said. “I usually go about three or four days nameless until I feel like it really connects with the baby.”

Kourtney Kardashian, a mother of three with ex-boyfriend Scott Disick, said it once took her a week to come up with a baby name, trying a different one each day.

She said son Reign was named “Preston” for a day.

“I was like, I know in my soul his name is Reign and Scott didn’t believe me,” Kardashian said. “And I was like, ‘No. I know his name is Reign.’ And he’s like, ‘His name is Preston.’ ”

But after a day of calling him by that name. it didn’t work out.

Kardashian West said she has been Googling Armenian boys’ names in honor of her family’s heritage but hasn’t really found anything.

She said that she was feeling she would name the new baby Rob after her brother, who approves.

“But then it’s kind of like North, Saint, Chicago, Rob,” she said. “It doesn’t really go, but I was really feeling that.”
