To celebrate daughter Stormi's Feb. 1 birthday, the mom of two shared a look at her Hello Kitty-themed sleepover

Now, Kylie has broken her photoshoot-heavy grid to drop the *cutest* video of Stormi and Aire in honour of their birthdays. The Webster kids, who were famously born just a day apart (Stormi on the 1st Feb and Aire on the 2nd), look so grown up in the video, which Kylie captioned: "my world. happy birthday to my babies."

Although Kylie Jenner grew up on reality TV, she made the decision to prioritize her kids’s privacy. The Kylie Cosmetics mogul doesn’t often post photos or clips of Stormi and Aire on social media for that reason.

Kris Jenner is doing a double Instagram dedication for her grandchildren, Stormi and Aire Webster, who both have birthdays this weekend. They are the kids of Kris Jenner's youngest child, Kylie Jenner and Travis Scott.
