InStyle's editorial guidelines Updated on February 5, 2018 @ 01:15PM Pin Share Tweet Email Two weeks ago, Kim Kardashian and Kanye West welcomed their third child, Chicago West, into the world, but she's already got a brand-new younger cousin to be her playmate. Kylie Jenner gave birth to her first child—a baby girl—on Feb. 1, and her big sis Kim took to her app in order to publicly share her feelings about it. Charley Gallay/Getty Images "Mommy Kylie!!! You did it!!! I'm so incredibly proud of the woman you have grown up to be and I know that you are going to be the best mom to your new baby girl!" she wrote in a post on her app. "Our girls are two weeks apart and I can’t wait for them to be besties! I am so proud that you do what you want to do and live your life the way you want, you will pass down all of those amazing qualities to your baby girl. You were made to be a mom! I love you!" While Jenner has not revealed her baby's name to the public (though fans certainly have their butterfly-related theories), little Chicago's name was announced two weeks ago by her parents.

If Kardashian's post is any indication, fans are likely in for tons of pictures of Chicago and baby Jenner in the future. Get ready for cuteness overload.
