Kardashian Children Rivals In The Making? Kourtney Kardashian Reveals Son’s Green-Eyed Reaction With The Arrival Of Kim Kardashian And Kanye West’s Baby

Despite their young age, rivalry seems to already exist in the Kardashian children. Just a few months after her birth, Kim Kardashian and Kanye West's baby has already gained abundant attention from the media. However, one of baby North West's cousins is not delighted with what's happening.

According to Kourtney Kardashian, her three-year-old son Mason thinks that he is not the family's center of attention anymore. Mason's closeness with her Auntie Kim similarly did not help. For the child, he can't help but be confused why his aunt is very much occupied with the new baby.

"He gets a little jealous because he and Kim were so close. He doesn't understand because he's not the big center of attention. He's like, 'Why don't you like me anymore?' I give him so much attention and he gets so much attention from everyone else that I don't even know," Mason's mom told People.

The 34-year-old mother also revealed that her younger sister Kim did not know how to handle Mason's jealousy fit: "I don't think [Kim] knows what to do; she's just like, 'You don't like me anymore?' She feels like he is getting older and changing, and I think she gets confused and doesn't know how to handle it."

On the contrary, the confused boy's 14-month-old sister has a different reaction: "Whenever [Penelope] sees [North] - the second she walks into the room, Penelope gets so excited. We never really had cousins that were close in age, so I'm excited."

Although currently living with some of her siblings in her mother Kris Jenner's mansion, Kim Kardashian will reportedly move to a newly-renovated mansion with her new family.
