Kourtney Kardashian’s belated birthday post for her son Rocky Thirteen proved to be worth the wait.

The Kardashians star marked her youngest child’s second birthday with a heartfelt and poetic tribute, which she shared on Instagram five days after his big day on November 1.

Taking to the social media account on Thursday, November 6, the Lemme founder shared an unseen and intimate photo captured two years ago in hospital shortly after Rocky’s birth.

In the caption she penned the touching verses from Nancy Tillman’s beloved children’s book On the Night You Were Born.

“On the night you were born

The moon smiled with such wonder

That the stars peeked in to see you

And the night wind whispered,

Life will never be the same.

Because there had never been anyone like you…ever in the world.”

The awe-inspiring passage continued, melting fans’ hearts, before the doting mother concluded with, “For never before in story or rhyme

(not even once upon a time)

Has the world ever known a you, my friend,

And it never will, not ever again…

Heaven blew every trumpet

And played every horn

On the wonderful, marvelous

Night you were born.”

Rocky is Kourtney’s first son with her husband Travis Barker. The couple, who tied the knot in 2022, share a blended family of seven children.

Kris Jenner’s daughter is also mom to sons Reign Aston, eight, and Mason Dash, 13, and daughter Penelope Scotland, 11, whom she shares with ex Scott Disick.

The Blink-182 drummer, meanwhile, is father to son Landon, 20, daughter Alabama, 17, and stepdaughter Atiana De La Hoya, 24, from his previous marriage to Shanna Moakler.
