The reality star and her husband Kanye West welcomed son Saint into the world last December and Kim admits three-year-old North is taking her time accepting she has to share everything with him.

Kim - whose sister Kourtney has three children, Mason, six, Penelope, four, and 19-month-old Reign - said: "We talk about North being a big sister all all the time. Right now, because she's three, it's time to talk a lot about sharing. And North is great at sharing. She's still getting the concept of having a brother, though. Like, Penelope and Reign are her cousins, but Saint is here every day because Saint is her brother."

But the 35-year-old beauty says she's working on the bond between her two children as she wants them to be close.

She told Elle.com: "I like to bring her in to say 'Good morning.' She still wants things to be all about her, because she's three! But planting that seed every morning that the day starts with you and your brother, that's how I've been doing it. And she's getting so much better. I can't wait until they can really start communicating - although once he's big enough to start grabbing her toys, we'll have to get involved in a different way."

And Kim admits she's used to siblings fighting over toys because she is one of six.

She said: "Of course that happened with us!"
