Those chubby little cheeks! Kendall and Kylie Jenner couldn’t get enough of their adorable nephew Reign on Saturday, Dec. 12, just two days ahead of the tiny tot’s first birthday.

“Me as a mom,” Kendall, 20, captioned a sweet snapshot of herself touting Reign on her hip while focused intently on her phone. In the photo, Reign — wearing a tiny jean jacket and black hood — looks at the camera, puzzled.

The model also previously posted a shot of Reign’s older sister, 3-year-old Penelope, in sunglasses and a top knot.

“Posh, my lovvveeeeeee,” she captioned the adorable shot, in which little Penelope tilts her head and grins at the camera.
