And today, exactly one week after their new bundle was born, Kardashian took to Instagram to reveal their son's name.
The reality star broke the news by way of an ultra-adorable snapshot of the newborn's tiny fingers wrapped around hers, captioning the pic, "Madly in love with my little Reign Aston Disick."
The moniker, of course, is a unique one. By definition, the name means "the period of time during which a king, queen, emperor, etc., is ruler of a country." The name certainly has a majestic flair and suggests a certain level of authority (or perhaps superiority).
But is little Reign about to kick off a royally popular baby name trend?
On Dec. 4 — two weeks before Kardashian and Disick announced their latest addition's name — NameBerry predicted the No.1 baby name trend for 2015 would be grand names that make big statements, like Reign.
And the fact that Kardashian chose the name for her child bodes well for that prediction. Following the birth of her first son, Mason, in 2009, the name shot from a ranking of No. 34 on the list of most popular baby names to No. 4.
Much of the same proved to be true in 2012, when Kardashian dubbed her baby girl Penelope — a name which, until then, was largely unranked on most baby name search engine sites. A year after her baby's birth, though, Penelope found its way to the No. 56 spot... and it's still climbing the charts.
Considering Disick's nickname is "Lord Disick," the couple choosing the name Reign for their third-born isn't altogether surprising. According to Hollywood Life, the name was entirely Kardashian's idea, in fact, and Disick actually wanted something more traditional.
So brace yourself — even though Reign is currently ranked No. 3750 on Nameberry, if Kardashian's trendsetting choices with her other children are any indication, 2015 may be a year filled with little heirs to regal names.
Think King, Titan, Baron, Noble, Royal, Princess, Prince and, yes, lots of little "Lords" named Reign.
