North West doesn’t like her brother Saint - Kim Kardashian

It seems a rivalry is brewing in the Kardashian West family home due to the differences between siblings Saint and North West as revealed by their mother Kim Kardashian West.

According to Kim, her daughter North, 4, is not a huge fan of her little brother Saint, 1, and it's apparently a problem that's not going away.

I don't know if it's because she's the older sister. I don't know what it is, said the 36-year-old reality TV star while co-hosting "Live with Kelly and Ryan" alongside Ryan Seacrest on Monday.

I thought it was a phase. She does not like her brother and it's so hard for me.

Kim went further to explain that jealousy is an issue for North when it comes to her younger brother, and she sometimes tries to box him out by inviting her (Kim) to girls-only tea parties. That means her father, rapper Kanye West, is excluded too.

She would get so jealous when I would breastfeed and all that kind of stuff, Kim said of North. And now, the phase isn't going away.

If she’s crying, then he’ll just start fake crying. I’m like, ‘One of you! I can’t pick up both of you and figure it all out! she said.

Kardashian, 36, and West, 40, are currently trying for a third child, after it was reported in June that the couple had enlisted a surrogate after doctors told Kardashian it wouldn't be medically safe for her to get pregnant again.
