The clip was taken during Kim and 39-year-old husband Kayne West’s “Soul Food Sunday” dinner party, with guests including Kevin Hart and Terrence J.
During the home-cooked feast, Kardashian West also shared a photo of Saint’s leg next to a child’s feet, which she captioned, “Cousin love.”
The Keeping Up with the Kardashians star has shared just three photographs of Saint since his birth in December.
