The 39-year-old reality star’s kids, daughter True, 5, and son Tatum, 15 months, took part in some fun with Rob Kardashian’s daughter Dream, 6, as the mom of two shared some adorable videos of the group on her Instagram Story over the weekend.

On Friday, Khloé shared a video of Tatum running through the house in a blue onesie while she cheered the smiley tot on, yelling, “Go, go, go!”

“Why are you running so fast?” she asks him in another clip, to which the 15-month-old replies, “Mama.”

In a following video, all three cousins piled onto each other, with True and Dream holding onto Tatum as they all smiled and wriggled together on the floor.

The playtime antics continued on Saturday when The Kardashians star shared more clips of the kids in action.

In one post, True smiled at her mom as she appeared to play a jumbo game of Jenga by herself.

The Good American co-founder also shared videos of Tatum playing solo, including a clip of him yanking a fence toy out of a pile of plastic horses, as another showed him standing by a doll house complete with a slide.

One other sweet black-and-white clip featured Khloé and Tatum laughing as the tot’s older sister tickled him.

Shortly after Tatum’s birth in June 2022, Khloé, who shares both of her children with ex Tristan Thompson, opened up to Elle about becoming a mother of two.

“I know it’s cliché, but I love everything, even the hard parts,” she said at the time, adding that the little ones “challenge me as a person,” and “being able to shape little people into really incredible big people is an honor and a gift.”

During a July 2023 episode of The Kardashians, Khloé also spoke about her relationship with her niece, Dream — the daughter of Rob, 36, and his ex Blac Chyna — whom she said she feels like a “third parent” to.

In the episode, Khloé welcomed guests to Dream’s butterfly-themed 6th birthday party, before she admitted in a confessional: “I feel like I’m like a third parent for Dream, I guess.”

“I mean I do know how important it is for Dream to have a great maternal influence, whether that be from me, or her own mom, or whoever,” she continued. “It’s important and whoever she gets it from, she gets it from.”
