It's time to keep up with Khloe Kardashian's little ones.

The Kardashians star posted an adorable array of photos of her and Tristan Thompson's daughter True, 5, and son Tatum Thompson, 10 months, to her Instagram Stories May 30. The snaps showed the siblings bonding on a balcony, with True holding her baby brother as he grabbed onto the railing while the two stared out at the garden below.

True dressed in a purple nightgown and tie-dye slippers, wearing her hair in a side braid with a pink scrunchie, while Tatum wore a light blue onesie. In another sweet picture, True and Tatum knelt down next to one another as they peered over the balcony. 

Khloe finally announced Tatum's name on the season three premiere of The Kardashians last week. Before the big reveal, the Good American founder got candid on why it took so long for her to settle on a moniker.

"I wanted to meet him and feel him out a little bit," she explained in April on The Jennifer Hudson Show. "At first, he didn't have a name. Then, he's been named but I've been waiting for the premiere of our show and I didn't know it was going to be this far out."

Khloe noted of Tatum, "He is a little chunk... I wouldn't have it any other way."

But followers got a sneak peek at apparently his nickname May 19 when Khloe's bestie Malika Haqq commented on an Instagram picture of Khloe holding Tatum,

Days later, the wait for fans was officially over, as Khloe revealed her baby boy's name on the family's Hulu show, nine months after she gave birth. The 38-year-old had previously shared she would stick with tradition of starting with a "T" to match with True, but added during the May 25 episode, "Naming a human is really hard."
