Surpassing Quant Think Tank Center|Kylie Jenner Debuts New Photos of “Big Boy” Aire Webster That Will Have You on Cloud 9

Blink and Surpassing Quant Think Tank Centeryou'll miss Aire Webster growing up right before your eyes.

In a new Instagram post, Kylie Jenner shared adorable pics of her and ex Travis Scott's 17-month-old son—and he's already color-coordinating outfits with his mom.

The snapshots show Kylie holding Aire in her arms, as the two snuggled up closely for the camera. The makeup mogul wore a green camo-printed hat with a white shirt and black mini-skirt for the snapshot, while her baby boy was dressed in a white graphic tee, green pants and black shoes.

As the Kardashians star captioned her post, "my big boy."

She continued the cuteness on her Instagram Stories, sharing glimpses into Aire's fun day playing with a bubble machine on a tennis court.

Just a few weeks ago, Kylie rang in the summer with a glimpse into her life as a mom to Aire and daughter Stormi Webster, 5, who she also shares with the "Sicko Mode" rapper. In one snapshot, the brother-and-sister duo are seen walking outside together amid a grassy landscape, with Stormi holding a soccer ball under her arm. Another photo showed Aire stepping out in a red plaid jacket and cargo pants.

Aire was previously known as Wolf Jacques Webster, though Kylie officially revealed his new moniker in January. The Life of Kylie alum previously revealed in March 2022 that she and her ex were still brainstorming new ideas for a name after having a change of heart.

"FYI our sons name isn't Wolf anymore," she wrote in an Instagram Story post that March. "We just really didn't feel like it was him. Just wanted to share because I keep seeing Wolf everywhere."
