We finally have our first glimpse of Kourtney Kardashian and Scott Disick's son, Reign Aston Disick!

And no surprise, he's even more adorable than we imagined. 

"My little turtle dove angel baby boy Reign Aston Disick," the proud mama captioned the aww-worthy photo on Instagram in which her sweet son is flashing a subtle smile at the camera (in case you're wondering, he's wearing bundl's Misty Grey onesie). 

Reign is the third child for longtime couple Kardashian and Disick. The little one joins 5-year-old big brother Mason as well as sister Penelope, 2.

The 35-year-old E! star gave birth to her bundle of joy back in December, and like her first and second, her pregnancy was chronicled on Keeping Up With the Kardashians

"I'm not getting a baby nurse," Kardashian, who appeared on the cover of Fit Pregnancy shortly before giving birth, told the publication. "I take two months off and no one is allowed to bother me or talk to me about anything work-related—or maybe three months this time."

"I love being pregnant in general," the brunette beauty, who, while expecting, posed completely naked for Dujour magazine, continued. "This time I'm more tired than I was the other times. I think it's because I'm always running around and working on different things. But I feel comfortable with how I look and feel. I find a pregnant body to be beautiful and an incredible reminder of what a woman's body is made to do."
