He's growing up so fast! Since giving birth to her third baby Reign Disick six months ago, Kourtney Kardashian has kept him under wraps, sharing only one photo of her adorable son on Instagram...until now!Scott Disick's better half showed off her son on Instagram in this pic, captioning it: "Three women and a baby." And luckily, there's no sibling rivalry between big brother and big sister Mason and Penelope. Scott told UsWeekly that everyone's getting along great since Reign's arrival.
"I really would have thought the other two would have been jealous," he told the mag. "They're so accommodating and welcoming -- I don't think I would have been that way if I had a sibling. I can not get over how much affection the other two have shown the baby."
Now we just need to see a pic of Reign with his siblings to see who he looks like the most. Do Kourt and Scott make some cute kiddos or what?
