She stopped by the late-night talk show to talk about the baby they're expecting.
"Baby number 4 on the way," she said. "I was kind of stressing that my house is so full, but I heard that parents of four are most enlightened and calm of all parents. The most calm, I heard that, so." The couple are expecting their fourth child via surrogate this year, and they previously also welcomed Chicago through a surrugote.
Kim believes that now parenting duties between her and Kanye will be evenly split.
"I felt the huge change from one to two, it felt like one to 20. That was harder than two to three for me," she said. "I feel like four is going to be really even though, because right now it's me with two and Kanye just has one, so he's still living his life and I'm like, you know."
Kim also has another thing to celebrate as her kids get older.
Her two oldest children are finally getting along. For years, Kim has talked about how much North disliked being an older sister but now she revealed the two little ones are bonding. "My 5-year-old daughter North and my 3-year-old son Saint are finally getting along. It's the best moment as a mom," Kim told Jimmy. She talked about Northie's only child syndrome in Ashley Graham's podcast in October 2018. “North acts like an only child at all times. I think she’s a little confused,” Kim said. “She’s beyond jealousy now. She’s just like, ‘It’s my world.’ She said to me the other day, ‘Mom, we just need to have another baby brother so that Saint can just leave me alone so the girls can be on this side of the house and the boys can be on that side of the house.’ "
