The issue was introduced because of her sister’s situation with her ex. Although Kourtney Kardashian and Scott Disick are no longer together, Kim thinks the former couple could have another baby together since they both want more children. This way, the siblings would all have the same parents. Kim started plotting the procreation:
“They don’t even have to have sex. It could be like IVF!”
Her reasoning comes from her own experience with her partner Yeezy. In the event of a breakup, Kardashian would have wanted some of his sperm as insurance towards the expansion of her family.
“I mean, I would want all my four kids with the same person. When I got pregnant with North, I had no idea if Kanye and I were going to end up together. I was like, ‘We can break up, but let me just at least have some sperm so I can have another one,’ so I could have siblings and then it will be all good.”
