Kim gave birth to North West, her first child with boyfriend Kanye West, last week and the 17-year-old model is happy to have a new niece to play with, reported Us magazine.
"I love kids, so it's so much fun for me. I bought a little pig for the newborn. They're all doing great, everyone's good," she said.
While Kim was preoccupied with her pregnancy this year, Kendall revealed her sister has been helping her in her career as a model.
Kendall isn't the only excited aunt in the Kardashian-Jenner household.
