Kendall, 17, has modelled for the likes of Chanel and Marc Jacobs, while Kylie has become something of a style icon worldwide.
Despite this, Kim, 34, insists they know what it’s like to be ‘normal’ teenagers.
She told Access Hollywood: “They are growing up with a life of privilege but they are super grounded and responsible.
“I have to think about it in a different way now that I have a daughter because she is born into it also and not by choice.
“So I think that having so many sisters that grew up differently than Kendall and Kylie and are always there to talk to them about things, they know when things aren’t normal.
“They know that all their friends aren’t going on private jets.”
But with all of her private jets and photo shoots, how does Kylie Jenner find the time to go to school?
“She’s home-schooled. She has a year left. She goes to school every single day.”
Someone should probably tell Kim that being home-schooled isn’t the same as going to actual school everyday…
