Tatum Thompson is up and moo-ving!
Amid the carousel of sweet snaps featuring Tatum, Khloe's daughter True, 5, and niece Dream Kardashian, 6, the Good American founder shared a video of the tot, dressed in a black and white cow onesie with matching Jordan sneakers, waddling around the house.
Other pics from the festive day included Khloe, also clad in a cow onesie, holding Tatum and group shot with True and Dream. She captioned the Oct. 15 post, "Until the cows come home."
Khloe's party comes days after she gave insight into the bond between True and Tatum, sharing a close-up pic of the siblings smiling and tightly hugging one another. The Good American founder simply wrote beneath the sweet post, "My babies."
Khloe has often detailed her life as a mom—both on social media and on The Kardashians. And that includes her co-parenting relationship with Tristan, whom she split with following multiple cheating scandals.
But despite their rocky romantic relationship, the pair have a solid foundation for raising their two kids together. (The NBA player is also dad to son Prince, 6, with Jordan Craig, and son Theo, 22 months, with Maralee Nichols.)
"What happened between Tristan and I was not some small, little incident," Khloe recalled during the Oct. 5 episode of The Kardashians. "It was some massive situation that really was a very traumatic experience for me in my life. So, I'm not gonna forget it. But, I'm so proud that I'm able to be kind and mature and show my children that Mommy and Daddy can co-exist and be co-parents and I'm able to be here for him when he's in his time of need."
