To celebrate Kourtney's birthday last week, Barker posted sweet Instagram photos of some of their most memorable moments, including glimpses of Rocky.

"Happy Birthday to my beautiful wife, soulmate and best friend forever. I love you, I love our life together. Thank you for being the most amazing wife a person could ask for. Here's to many more years of adventures together ❤️‍🔥" the Blink-182 drummer wrote in the caption of his post.

The sweet dedication also included a shot of Kourtney as she smiled, cuddling with their baby in bed. Another photo showed the proud parents kissing in front of an airplane while Barker held Rocky in his arms. The little one wore striped black pajamas that matched his mom's.

Kourtney is mom to daughter Penelope Scotland, 11, and sons Mason Dash, 14, and Reign Aston, 9, whom she shares with ex-Scott Disick. She is also stepmom to Barker's daughter Alabama Luella, 18, son Landon Asher, 20, and stepdaughter Atiana De La Hoya, 25, who he shares with his ex-wife Shanna Moakler.

After baby Rocky's arrival, Kardashian Barker shared how her priorities have shifted since welcoming her son.

“Getting dressed postpartum while breastfeeding=throwing on an oversized coat, flat shoes pretty much always, loves leggings, sweats, anything baggy and comfortable aka husband’s vintage t shirts and dickies," the mom of four wrote next to an Instagram Stories photo of herself in February.

“And anything super fast to throw on=less time away from my baby the better..." she continued.
