And while mom Kim Kardashian isn't shy about sharing photos of herself on Instagram, she's much more selective when it comes to photos of her daughter. That is, until she just uploaded this treasure trove of insanely adorable pics of North with her cousin Penelope Disick for Penelope's birthday.
First, she hit us with a little bit of a throwback, where North is SO tiny:
Then, she shared this precious pic of Nori and Penelope feelin' the pain of each other's owies:
"These wild ladies always help each other when they have boo boo's! #BFF'S #HappyBirthdayP," she captioned the too-cute-for-words snap.
Kim definitely saved the best for last, though, sharing this photo of the little ballerina BFFs on the playground together.
We know Kim did this for Penelope's birthday, but we feel like we're the ones who got the gift of seeing these absolutely adorable candid moments of the super cute cousins.
