Because of its simplicity, hide-and-seek is a universally played children's game. But when kids start playing the game, they're typically at an age where they struggle with the hiding and seeking aspects. YouTube user Dan Iverson uploaded a video which confirms this. He and his wife put a GoPro on their toddler and watched as their son attempted to find them. There's a lot of looking in open spaces. 

"I love how you can tell he's thinking," the dad wrote in the video. "We were watching the live preview on my phone and laughing so hard."
