According to reports, the superstar couple have begun thinking about when to expand their family, since they are both keen to have a large brood.
And they may even start trying for baby number two as soon as next year, once they've walked down the aisle.
A source told US Weekly: "[Kim will] try to get pregnant next summer, after the wedding."
Given that Kim comes from a huge family herself and has five siblings, as well as four step brothers and sisters, it's no surprise that she might be eager to give her daughter North a sibling too.
And Kanye has echoed Kim's sentiments, with the US Weekly source claiming that he wants to have many children.
Plus, the two stars appear to be taking to parenting like ducks to water.
Last weekend, Kim couldn't resist gushing about 5-month-old North in a Twitter message that read: "Mums- do u ever want to wake up your baby to give him or her kisses? i want to soooooooo bad right now, but she's so peaceful sleeping."
According to E! Online, however, any talk of a baby is too soon and Kim, Kanye and North are perfectly happy as a trio right now.
Aside from being a parent, Kim will have plenty on her plate next year as she plans her extravagant 2014 wedding.
Kanye got down on one knee in a lavish proposal on Kim's 33rd birthday last month.
Not only did the Yeezus rapper rent out an entire baseball stadium for the occasion, he also hired an orchestra to serenade the couple and had the words 'Please Marry Me' lit up on the stadium's big screen.
And if that's just the proposal, then imagine what the wedding will be like!
However, Kim is taking a back seat on this one and has been heard saying that the plans for their upcoming nuptials will be left to her man.
But with Kanye recently admitting that he wants to have fighter jets at the ceremony, Kim might want to re-think how much input she intends to have!
