Reign resurfaces! Though Kourtney Kardashian and her famous sisters have had no problem sharing pictures of Kourt’s oldest kids, Mason and Penelope Disick, fans don’t get to see her youngest, baby Reign Aston Disick, 9 months, quite so much. 

But the tiny tot made a cute cameo on his mom’s Twitter page on Wednesday, Sept. 23. 

“Yellowstone National Park. #lonemountainranch #justcallmedavycrockett,” Kardashian, 36, captioned a photo of herself wearing a coonskin cap and looking up at the mountains while Reign sits in her arms looking back at the camera. 

Earlier in the day, Kourtney shared a photo from what appeared to be a rigorous obstacle course. In the pic, she’s climbing up a tall rope ladder. 

She believed she could so she did.

“She believed she could so she did,” she captioned the photo. 

While mom’s off in the mountains, Penelope, 3, and Mason, 5, have been enjoying some time with their aunts Kim and Khloe and their youngest cousin North West, 2. 

Kim shared a photo of the group in a car ride together with North and Penny holding hands, writing, “ROAD TRIPPIN’.” 

Kourtney’s been embracing the single life since her split from her longtime love of nine years, Scott Disick, in July. The pair parted ways after Scott was photographed getting too close for comfort with his ex-girlfriend Chloe Bartoli in the South of France.
