The 36-year-old reality star has revealed her four-year-old daughter North has still yet to completely "warm up" to her 22-month-old younger brother, but insists that she's not being "harmful" towards the tot, and she simply just "doesn't want boys in her room".
In a new video with her grandmother Mary Jo 'MJ' Shannon, which was posted to her app, the 'Keeping Up with the Kardashians' star debunked rumours that North "does not like" Saint.
Kim - who has both her children with her husband Kanye West - said: "Obviously North loves Saint, she just is still jealous. She needs to still get it together and warm up and be a little bit nicer, but I think she's getting there. I saw glimmers of hope a week ago. She's not harmful, she's not hurting him or anything. She just doesn't want boys in her room."
The brunette beauty's comments come after she claimed in an interview in August that she finds it "so hard" to deal with her brood when they don't get along.
She said: "I don't know if it's because she's the older sister. I don't know what it is. I thought it was a phase. She does not like her brother and it's so hard for me. She would get so jealous when I would breastfeed and all that kind of stuff. And now, the phase isn't going away."
Kim and Kanye, 40, could be in for more troubles with sibling rivalry in the near future, as they are expecting their third child together, who will be born via a surrogate mother after Kim suffered complications with her previous two pregnancies.
And her famous family - including mother Kris Jenner, sisters Khloe and Kourtney Kardashian, brother Rob Kardashian, and half-sisters Kendall and Kylie Jenner - are said to be "genuinely happy" about the news.
A source said: "They're focusing on the babies. Everyone is genuinely happy about what's happening."
