Kim Kardashian hopes baby #4 will be 'really even' as she made a rare confession about her unborn

Kim Kardashian and Kanye West are expecting their fourth child and cannot wait to welcome the little sprout into the world.

Kardashian appeared on the Jimmy Fallon show last week, and Fallon used the opportunity to ask some questions about the new arrival to the family.

Kardashian and West are expecting their fourth child, a boy, via surrogate and mother-of-three was open about her slight anxiety of increasing the size of their family to six.

“I was kind of stressing,” Kardashian West told Fallon. “My house is so full [but] I heard that parents of four are the most enlightened and calm of all parents.”

Kardashian also admitted to Fallon that the biggest adjustment thus far was when the three-year-old Saint was born.

Going from a single child – North – to a family of four immediately meant more juggling to keep up with the children's needs. She added:

“I felt the huge change — from 1 to 2, that was harder than 2 to 3.”

Their third child, Chicago, recently turned one, and Kardashian said Saint and North are "finally getting along."

There is always a bit of sibling rivalry going on between to the two, with North being the culprit when she's mean to Saint.

The couple went the surrogate route once because Kardashian experienced placenta accreta in her previous pregnancies.

At the very least Kardashian felt that the new addition would even the numbers out giving Kanye a bit more work to do around the house. Kardashian explained:

“She needs to get it still 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 couple went the surrogate route once because Kardashian experienced placenta accreta in her previous pregnancies.

The condition occurs when the placenta or a part thereof remains connected to the uterine wall after childbirth and leads to severe blood loss.
