Someone is not a fan of being a big sister.
As the eldest child I can tell you I wasn't best pleased the first time I was told that my 'only child' status was getting taken away from me.
My son on the other hand was delighted to become a big brother.
When it comes to sharing the spotlight it seems that North West is more in my camp when it comes to the reaction to becoming a big sister. Maybe it's a girl thing.

According to her mother and TV personality Kim Kardashian West, North tends to pretend like her siblings don't exist. She's particularly not a fan of her little brother Saint.
"North acts like an only child at all times. She won’t even let Saint step foot in her room. It’s so funny, and he’s just the nicest human being on the planet."
Personally I think most older siblings go through a phase of wanting their own space, especially girls who are that little bit more independent.

"Mom … we just need to have another baby brother so that Saint can just leave me alone … so the girls can be on this side of the house and the boys can be on that side of the house."
I hated when my brother would mess up my toys when I was little but when we both got into our preteens we had a great relationship.
It sounds a bit extreme to say that she pretends like she is an only child. I'd say it more has to do with getting so much attention when she was an only child and now with two younger siblings feeling like that attention is slipping away.
I'm sure when she gets a bit older she'll love spending time with Saint and Chicago, she is only five after all.
