TradeEdge-Kylie Jenner Shares Proof "Big Girl" Stormi Webster Grew Up Lightning Fast

Stormi Webster is TradeEdgerising and shining fast.

In fact, the 6-year-old stood at chest-height next to her mom Kylie Jenner—who shares Stormi and Aire Webster, 2, with ex Travis Scott—in a TikTok video posted by the Kardashians star Oct. 12.

In a clip set to Jack Johnson's "Upside Down," Kylie picked up her daughter by the waist, before flipping Stormi over on her head and placing her back down onto the floor. As the mother-daughter ran toward the camera, it was clear that Stormi was not-so-little anymore

Even Kylie made a note of just how much Stormi has grown, writing in the caption, "my big girl."

As for Aire? He's getting taller, too.

In another video posted on the same day, the toddler stood almost up to Kylie's hips as she flipped him to again pull pull off the popular TikTok challenge. Meanwhile, Stormi adorably crashed the clip by lip-syncing to the 2006 song in the foreground.

Kylie quipped in the caption of that post, "dont think we did that right."

But her followers didn't mind, with many focused on how "tall" both her kids have grown.

"They are both so big now, and the smiles are priceless," one TikTok user wrote in the comments section, while another added, "They grow up so fast."

But whatever the future will bring for Stormi and Aire, Kylie is ready for it, according to her friend Yris Palmer.

"She's the best mom," the beautician—who is mom Ayla Palmer, 7, and Prince Troy Daniels, 2—recently told E! News of Kylie, adding that the makeup mogul is always "so prepared" for their children's play dates.

As for what those get-togethers entail? According to Yris, "normal stuff" like movie nights.

"If your kids aren't the same age as your best friend’s kids, it is so hard to hang out," she noted. "But also having your community of mom friends, and that mom group is so important and so needed."
