Khloe Kardashian is keeping up with her kids’ major milestones.

As her and ex Tristan Thompson’s kids True, 8, and Tatum, 4, head back to school, the Kardashians star shared a glimpse into how they marked the occasion, as well as a sweet commemoration of their journey so far.

“I canNOT believe Tatum started school today! And my True is in THIRD GRADE!” Khloe wrote alongside a Sept. 2 Instagram carousel of photos. “Both of my babies are officially in school and I truly don’t know how we got here.”

In her post, the 42-year-old shared sweet photos of her kids smiling for the camera as they showed off their first day of school attire.

And Khloe pulled out all the stops for the special day. After all, the family posed in front of a colorful school-themed decorative balloon display—complete with inflatable pencils, markers and apples, along with a large chalkboard.

While Khloe couldn’t be happier for True and Tatum to embark on a new adventure, she’s feeling emotional about how fast they’re growing up.

“I’m so grateful for every milestone, but man… it is such a trip how quickly it all goes by,” she shared in her caption. “In a blink, they’re suddenly a little bigger, a little more independent, and becoming more and more of who they are meant to be. God is incredible for blessing me with such special angels.”

The Revenge Body alum then asked, “How do I make it all slow down just a little?”

Khloe ended her heartfelt post by expressing her limitless love of her kids.

“I love my babies beyond words and I am so incredibly proud of the souls that they are and all that they are becoming,” she concluded. “I love you so much my cuties! I can’t wait to see what this school year brings.”

And Kris Jenner couldn’t help but take the opportunity to praise her daughter on her motherhood journey.

“You are the most amazing Mom,” the matriarch commented on Khloe’s Instagram post, “and your children are so incredibly blessed to have you as their Mommy!!!!! You make every single day a celebration !!”

As True and Tatum reach new milestones as they grow up, Khloe continues to prove that she never fails to celebrate each and every one of them.

Indeed, Khloe recently transformed her house into a Zootopia-inspired wonderland for Tatum’s 4th birthday in late July, giving fans an inside look at the epic “Tatumtopia” celebration on her social media.

She also shared an adorable video tribute to her little one, posting a montage of clips of Tatum from over the years, captioning the July 28 Instagram post, “Happy 4th birthday my angel boy.”
