Over the summer, Kardashian celebrated daughter Penelope's 10th birthday with a sweet tribute on Instagram.
"I feel so blessed to be the mommy of this little lady," she wrote alongside a carousel of photos featuring herself and Penelope, as well as some of their friends and family.
"She makes me so so proud every day and brings so much joy to my world," the Poosh founder continued. "Happy 10th Birthday my Penelope 💞🥳"
The Kardashians star also noted in the post that her daughter's birthday festivities were "filled with matching pajamas, fuzzy slippers, all sleeping together in blow up hearts, outdoor movies and lots of rainbow sprinkles."
In one snap, Penelope joined some familiar faces in the Kardashian-Jenner circle, including cousin North West and Jessica Simpson's daughter, Maxwell Drew Johnson, as the group struck funny poses with a beautiful sunset in the background.
The reality star also shared a picture of the birthday crew lounging in the backyard in pink, heart-shaped blowup pools that served as comfy lounges while watching the new Minions: The Rise of Gru film on the big screen.
