In it, the mother of three showcased her two oldest children, Mason, 6, and Penelope, 3, in a throwback pic, in which they are sprawled out in matching pajamas napping next to their mom, who was still pregnant with Reign (now 1) at the time.

While Kourtney is known for putting her three kids first and could be considered a homebody next to her four socialite sisters, she's got more than just naps and afternoon hikes up her sleeve. In fact, it was just this week that Kourtney started getting daughter Penelope into the beauty game—and we've got the photo evidence to prove it. Looks like it won't be long before her kiddos will be taking after their trendy mama and her chic sisters in the style department.
