slumber party 🎀

A post shared by Kylie (@kyliejenner) on

BFFs in the making!

Cutie cousins Stormi and Chicago had a sleepover the other night at mama Kylie Jenner posted this adorable pic of the cousins' first overnight together and captioned it, "Slumber party."

“My babies!” mommie Kim Kardashian commented on the pic; auntie Khloé Kardashian posted: “Honestly I just can notttttt!”

Where was Khlo's baby True? She was MIA, but perhaps she'll be at the next one.

And yes, Kim and Kanye's daughter Chicago is holding a tube of baby cream ... we're guessing she didn't eat it, so calm down mom-shamers!
