Kourtney Kardashian has revealed the first photo of her son Reign. The “Keeping Up with the Kardashians” star went on Instagram to show her son to the world. “My little turtle dove angel baby Reign Aston Disick,” she wrote in the caption.

Technically, Kardashian, 35, and her partner Scott Disick, 31, shared a photo on Instagram the day Reign was born. However, the picture only showed Reign’s tiny hand.

At 3 months old, Kardashian made fans wait the longest for pictures of the youngest Disick. Her other children were revealed to the public much earlier. Penelope, now 2, had a slightly more glamorous debut than her brothers in 2012. Just a month after she was born, the first pictures of her made it onto the cover of Us Weekly.

Mason’s debut was a little more low-key. Kourtney’s eldest, now 5, was introduced via some family portraits at 1 month old in 2010.

So why wait three months to introduce Regin to the world? His reality star mom may have been a little too busy to think about introducing him earlier. Kardashian’s personal and professional life has been a little hectic. Between Scott Disick’s trips to rehab, taking care of three kids and a new season of “KUWTK” in full swing, the TV personality may not have had time to set up a professional photo shoot.

This may be the last time Kardashian gets to reveal a new baby. Recently, Disick was asked by E! Online if they would have more kids and he said, “Probably not.”
