Kourtney Kardashian Barker's son Rocky is growing up in style.

On Wednesday, the Lemme founder, 44, shared a carousel of photos on Instagram featuring a few peeks at her baby son Rocky Thirteen, 4 months, whom she shares with husband Travis Barker, 48.

The famous couple can be seen walking their son as he rests in his blue Cybex stroller, which she highlights in a later slide.

At the end of the post, Kardashian Barker showed off the epic stroller in its entirety. The teal and silver stroller looks like a normal carrier at the front, but the back sports taillights and a bumper, taking inspiration from a vintage car.

The mom of four also included a close-up of her toddler son's hand as he played with his dad's necklace, as well as a picture of herself pumping in a lacy bodysuit. "That's life," Kardashian Barker simply captioned her post.

Along with son Rocky, Kardashian Barker is mom to daughter Penelope, 11, and sons Reign, 9, and Mason, 14.

In March, Kardashian Barker rounded up her time in Australia in a series of photos shared on her Instagram. The proud mom shared pictures with her son Reign and daughter Penelope as they enjoyed their time down under, as well as a photo of Rocky's tiny foot while they flew home.

"Feeling so grateful for every single second of time with my babies," the proud mom wrote in her caption. "Rare to get 2 full weeks of 24/7 time as they get older! Thank you Australia for the beautiful memories (minus the spiders)."

While Kardashian Barker and her husband have yet to show their son's face, Rocky has appeared in a few photos on Instagram, including when Barker ended his Blink-182 tour. The family was in Australia and New Zealand to support Barker's band.

In one sweet photo, Rocky’s small foot rested on Barker's drum beside his drumsticks. “Tour was over, we’d survived,” Barker wrote in the caption.

Kardashian Barker and her rocker husband welcomed their first child together in November. Besides Rocky, Barker is dad to daughter Alabama Luella, 18, and son Landon Asher, 20, and stepdaughter Atiana De La Hoya, 24.
