"My little turtle dove angel baby boy Reign Aston Disick," Kourtney captioned the image that shows him in a white onesie with his arms up, almost as if he's flexing.

Although he was born on Dec. 14, neither Kourtney nor daddy Scott Disick (or any of their famous family members) have shared a full image of Kourtney and Scott's third-born child, until now. Previously, Kourtney had only shared a picture of Reign's hand.

Welcome to the social media world, Reign!
