Aire Is 1! See Kylie Jenner's Racecar-Themed Birthday Party For Her Son

Time flies when you're turning 1. Only a few weeks after publicly revealing her son's name, Kylie Jenner gave her second child an unforgettable first birthday. Her baby boy, named Aire, started his day off with a gigantic ball pit rivaling a swimming pool in terms of its size. "Aire day today," Jenner wrote with a photo of the pastel ball pit and racecar balloons scattered throughout the house.

But of course, the extravagance didn't stop here. The Kylie Cosmetics mogul also had merchandise made in celebration of the two Webster kids, whom she shares with Travis Scott. Seeing as their birthdays are only one day apart, Stormi and Aire shared some parts of their special days with one another. Attendees were given hoodies reading "It takes two" and featuring a metallic illustration of the siblings holding hands. Jenner also posted a photo of T-shirts reading "Stormi Five Is Live" and "Aire to the Throne."

Fans may already be familiar with the giant inflatable Stormi head formerly used at her StormiWorld-themed birthday party. It appears that this year, Aire received a version of his own, the colossal silver mouth appearing to swallow a racetrack aisle runner. According to Jenner's photos, Aire was also gifted at least three mini vehicles to practice his driving, and even his cake was constructed in the shape of a blue racecar.

"AIRE. my son, my moon, my stars. best year of my life with you," Jenner captioned an Instagram video made up of clips featuring her and Aire. "You complete us my angel. mommy loves you. happy 1st birthday. may God always bless you." Read on to see exactly how Aire rang in his very first birthday.
