Less than a day after shutting down rumors that Saint West was never real [1], Kim Kardashian took to Instagram on Saturday to share a video of the tiny tot adorably laughing. In the clip, Kim is shown tickling Saint with a stuffed animal, causing him to burst into sweet laughter. The video is just the latest we've seen of Saint [2] in the past couple of months, though Kim often takes to Snapchat to share sweet family moments [3]. We hope you don't need your heart back anytime soon because it's about to melt.
