Dubbed 'StormiWorld' it was a lavish theme park style affair that must have cost thousands of dollars.
In respect to father Travis Scott's 'Astroworld' the celebration had a live Baby Shark performance plus carnival rides and designer fries for the kids to enjoy.
"I had to go all out for my baby," Jenner admitted on Instagram alongside a sweet mother-daughter photo from the bash, adding the hashtag #StormiWorld.
Stormi's original party on February 1 had to be cancelled because of the rain son Kylie, 21, threw a second one.
The entrance to the party featured a giant blow-up replica of Stormi's face that welcomed guests inside the venue.
Once inside, guests walked through a room filled with inflatable balloon clouds (referencing Stormi's name) and carnival rides.
Other rooms in the venue included a bubble room, "Stormi's Shop" (filled with Stormi-themed merchandise) and a magical "butterfly forest" room.
There was also lavish treats for people to enjoy and some seriously fun gift bags also for the other kids to take home.
Kylie and Travis Scott are expected to attend the Grammy Awards later tonight amid rumors they will get engaged and that she is expecting a second child.
