The Kardashian-West family had a bittersweet Christmas as the couple found out that the chances of them having a second child are very slim. It turns out North is a miracle baby but may also be an only child, despite Kim and Kanye's attempts to conceive another child.

Kim and Kanye have been trying to become pregnant again for nine months to no avail, reports TMZ. It appears the reason is medical, and Kim may not be able to have children ever again, at least, not naturally. The three specialists she has consulted with all agree another child is very rare; nonetheless, Kim has gone into a new routine to relieve stress and cut down on traveling, in hopes it may change things.

According to the New York Daily News, Kim's most recent interview with Elle UK reveals more about her pregnancy issues.

"A few years ago I was told I could never get pregnant," she told the magazine. "Three different doctors told me the same thing, which is why I wanted to have my eggs frozen. I was just about to do that when I found out I was pregnant with North."

Regardless of the complications, she and Kanye will continue trying to have a baby, doing whatever it entails to make it possible. She hopes to have an additional boy and girl.

"I loved being part of a huge family -- and I want that for North," Kardashian said. "We'd do IVF if nothing happens, but we both want to keep trying naturally."

However, some sources say Kim has been taking out her frustration on her sister Kourtney, reports Hollywood Life.

"Kourtney basically can blink and have a baby, and now that Kim is having trouble she is extremely jealous and is not hiding her emotions about it to Kourtney," the unnamed source told Hollywood Life.

"It's driving Kourtney crazy because along with dealing with the nonsense that Scott puts her through and her mom puts her through, now she has to deal with a jealous sister to add to the stress."
