"Who's singing this?" the 37-year-old mother of three asks her baby boy. As Kim puts her hand under her son's chin, Saint -- dressed in a neon green shirt and wearing a captain's hat -- sweetly replies, "Daddy." Kim then continued by rapping her husband's lyrics, as her son kept chatting.
Just a day before, Kim shared a too cute video of little Saint dancing on top of a chair at the lunch table. The tiny tot is wearing a camouflage red shirt with red shorts and waves a napkin over his head before tossing it behind him.
