On his Instagram, Travis, 48, shared some new snaps while enjoying a tropical vacation with his family – including Kourtney, 45, and his daughters Alabama, 18, and Anita De La Hoya, 25.

Travis also has a 20-year-old son named Landon.

However, Travis’ first snap grabbed the most attention as it featured his six-month-old son.

In the short clip, Travis and Rocky enjoyed some bonding time at the beach.

The pop-punk rocker held onto his son while the tiny tot splashed in the crystal-clear water.

Travis was recorded wearing a checkered bathing suit and a black hat to shield his face from the sun.

Meanwhile, little Rocky wore a beige onesie and a green bucket hat while feeling the warm water and gooey sand.

‘THIS IS SO PRECIOUS!’

“Grateful,” he captioned his post with Kourtney commenting, “A beautiful life.”

More fans left comments in awe over Rocky’s appearance.

“The chunky leggies and feets,” one wrote.

Another said, “So happy for Kourtney getting to experience having a baby with someone that loves being a parent as much as she does. So special.”

“This [is] precious! The ocean is such a gift and I love that you’re sharing it with your son at an early age,” a third exclaimed.

“Baby Rocky is getting so big,” mentioned a fourth follower.

SHOWING OFF

During her relaxing vacation, Kourt has been showing off her post-baby body.

Last week, Kourtney shared a carousel of photos and captioned them, “It’s better in the Bahamas.”

In the first snap, the TV personality showed off her toned legs in only a blue oversized shirt while riding a bike on a beautiful sunny day.

Just a few days prior, Kourtney flaunted her curves in a post celebrating her birthday.

The Kardashians star turned 45 on April 18.

She wowed fans by posing in a colorful bikini as well as a loose-fitted shirt with her son, Reign, making an appearance.

Along with Rocky, Kourtney shares Mason, 14, Penelope, 11, and Reign, nine, with ex Scott Disick, 40.
