In a new blog post, Kim further explained why she's bit nervous for little boy West to enter the world. "Not going to lie, I’m a little nervous about bringing baby No. 2 into the mix. But Kanye and I are doing the best we can to prepare ! We read books with her about getting a baby brother and a new sibling all the time! We always say goodnight to baby brother. And right now anything her cousin Penelope does, she does. So it’s really helpful that P has a little baby brother!!!” she explained on her website.
