Kim dropped a quick hint about what the theme of Chi's party would be on her Instagram Saturday by showing the entrance to it as key shaped.
A girl dressed as Alice from the classic novel and movie appeared right when she walked inside.
Chi's big brother Saint was being super helpful during the party. Kim took an IG story of him sharing his cup of water with his little sister.
Kim mixed Alice in Wonderland with one of her family's catchphrases, as she showed a variety of Alice-related dolls hung up with "Thanks Doll" on the top.
She also got an Alice in Wonderland themed cake, which included an adorable Chicago teapot above the Cheshire Cat.
