“Kim is really into the idea of a bunch of babies being born around the same time,” the source said. “She thinks they’ll be more like sisters than cousins. Everyone in the family is just thrilled about the whole thing.”

Which isn’t to say that Jenner’s pregnancy didn’t catch everyone off-guard. “No one was thrilled about Kylie because she’s so young and naïve,” the source continued, “but everyone has come around and they are focusing on the baby.”

“They truly believe that Kylie will rise to the occasion and be a good mom,” added the source. “And they’ll be there to help!”
