The mom of two shares Tatum and daughter True, 6, with ex Tristan Thompson.

Earlier this month, Kardashian shared a sweet snap of her son as he gave his older cousin Saint, 8, a hug. The two boys both wore white shirts, smiling together as they sat at a table.

"I was going through my camera roll and I came across this photo of Saint and Tatum. Saint is the absolute sweetest when it comes to babies, but his connection to Tatum is one that can’t be explained," Kardashian wrote in her caption.

"They were destined to be in one another’s lives! Proud auntie! Proud mommy! 🥹🤍."

"Sainty loves Tatum so much! We all do 🩶🩶," Saint's mom Kim Kardashian, 43, wrote in the comments.

At the end of August, The Kardashians star shared several adorable pictures to Instagram of herself, True and Tatum posing in front of a giant pastel crayon balloon arch in honor of True's first day of first grade.

True could be seen smiling in her school uniform with her cat in her arms, while her mom got emotional over the milestone in her caption.

"First Grade!!! True I am so proud of you!!" she shared. "I know you’re going to have the most incredible year ahead of you! I couldn’t be happier for you my angel."

She continued to admit, "I’m not ok but I’ll pull it together by pick up time 🤍."
