Kim is expecting her second child with husband Kanye West in December. And in a new post on her blog, Kim opened about how she is preparing her daughter North for the impending arrival.

According to her, Nori, as she's affectionately known by her family, is prone to a little jealousy when other children are around her mom. She doesn't like it when Kim holds other babies. So Kim is a bit apprehensive about introducing her to her little brother.

The 35-year-old star wrote:

'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 North! We read books with her about getting a baby brother and a new sibling all the time! We always say goodnight to baby brother.

I know it it won't be easy—North even has a hard time adjusting when I hold other babies!' 

Thankfully being part of such a big family is a blessing for the reality star as she explained that North's cousins, namely her sister Kourtney's daughter Penelope, act as great role models for her daughter.

'Right now anything her cousin Penelope does, she does. So it's really helpful that P has a little baby brother!!!' she said.

The KUWTK star wrote that she is spending as much time with her little girl as possible as the time is quickly running out before the family of three becomes four.

'I'm really trying to spend most of my time at home so we have this special bonding time. Any other moms have this nervous feeling?'
