Kim Kardashian and Kanye West are set to welcome their fourth child via surrogate this year, and with the due date creeping ever closer, the Keeping Up With the Kardashians star has been feeling both excited and nervous about expanding her family.

“I was kind of stressing, my house is so full,” Kardashian West admitted to Jimmy Fallon on the Thursday, February 8, episode of The Tonight Show. Then, joking, she added, “But I heard that parents of four are the most enlightened and calm of all parents.”

She went on to tell Fallon how her family has been managing the transition to a bigger brood. “I felt the huge change from one [child] to two,” Kardashian West said of her older children, daughter North, 5, and son Saint, 3. “It felt like one to 20! That was harder than two to three.” (She and West welcomed daughter Chicago in January 2018.)

Reports that the KKW Beauty founder and her husband were once again expanding their family first surfaced in early January. Kardashian West confirmed the news a couple of weeks later in a low-key way on Watch What Happens Live With Andy Cohen, saying that the baby boy was due “sometime soon.”

It has been reported that the famous couple are using a different surrogate than they used for Chicago, but the couple has neither confirmed nor denied that rumor.
