What a little cutie!

Kourtney Kardashian is enjoying every second of her vacation in Montana with her close pals, and it looks like little Reign Aston is having a ball as well! We don't get to see much of the tot, but he's certainly growing up quickly! We feel like just yesterday Kourt gave birth to her third child. While mom and baby were busy scoping out buffalos on the open plains, Mason and Penelope were being babysat by Kim and Khloe and hanging with North West.

Meanwhile, baby daddy Scott Disick doesn't appear to miss his family at all. The Lord is currently in NYC, and based on his Instagram, he's just lunching with friends and taking it easy. Has LD even spent any time with Reign since he was born? We doubt it!
