"Happy Mother's Day to my best friend and partner," the  drummer posted online on May 12. "Our children are so lucky to have you. Thank you for filling our home with love, laughter, and joy. I love you forever and ever my wife @kourtneykardash." 

Accompanying his message, Barker, 48, shared endearing photos of Kardashian with their baby boy, Rocky Thirteen Barker. One captured a tender moment of 'The Kardashians' star cradling the 6-month-old in a gray onesie, while another showcased the duo donning matching white robes.

Additional snapshots depicted Kardashian, 45, and Rocky lounging in bed, the little one comfortably seated in his stroller. However, in a gesture to safeguard the privacy of the little one, both the Poosh founder and the musician shielded Rocky's face from the camera.

The Blink-182 member also shared a snapshot of himself and his wife exchanging a warm embrace on a boat, as well as one capturing her snapping a cozy selfie in pajamas and fuzzy slippers. The reality star reciprocated the Mother's Day sentiment, expressing her love for Barker in the comments: "I love you forever and ever my husband." 

Barker's tribute post wasn't the sole gesture of celebration for Kourtney, who also co-parents children Mason Disick, 14; Penelope Disick, 11; and Reign Disick, 9, with ex Scott Disick. Barker gifted her multiple lavish arrangements of roses.
