Kim Kardashian West would be lost without having her sister Kourtney to copy.
Kourtney Kardashian and Kim Kardashian West
The 35-year-old reality star admits she mimicked everything her 36-year-old sibling - who has kids Mason, six, Penelope, three, and Reign, 13 months, with former partner Scott Disick - did when they were growing up and even now she turns to her for inspiration on raising her and husband Kanye West's two children, North, two, and Saint, nine weeks.
Kim told Britain's Cosmopolitan magazine: "I don't know what I would have done if I'd been born first. I copied every single thing Kourtney did...
"She taught me everything.
"And as a mum myself now, I call her for everything. It's exactly like how we were before: I just copy Kourtney."
Kim has learned a lot from her "brave" sister, who helped her navigate fame in the early days of their family reality TV show 'Keeping Up with the Kardashians'.
She said: "She is the most practical one-stable and calm.
"I'm not really a fearless person, but I think Kourtney is the bravest. In the beginning of the show, when I thought little things were such a big deal, she made me realise they weren't. She taught me that it's not worth wasting energy on things that don't matter."
And just as Kim copied Kourtney when they were children, things have come "full circle" as her little girl North looks up to her older female cousin.
Kim said: "And my daughter wants to do everything Kourtney's daughter Penelope does. We've come full circle."
