In photos and videos posted to her Instagram story, Kylie revealed snippets from the kids’ big days.

Stormi’s birthday included a room completely filled with balloons, a birthday cake covered in metallic frosting and flowers, a rainbow bouncy slide, multicoloured balloon arches and glittering streamers, and at least two giant silver inflatables of Stormi’s face. (One of the inflatables was so big that Stormi’s mouth served as a tunnel that led to the party festivities.)

On Aire’s birthday, Kylie also got her son a giant inflatable head, as well as race car-themed decor complete with a race track walkway, a race car birthday cake, and kid-sized car and motorcycle toys.

The inflatable faces pay homage to dad Travis, who used giant gold replicas of his own head to promote his album Astroworld back in 2018.
