I mean, come on. They do. Even yours. As to why “babies look between their legs” (which at first I didn’t get – I was like, “To see if they’re a boy or a girl?”), apparently there’s an old wive’s tale that says when a toddler bends over and looks at the room upside down between their legs, someone in the room is pregnant. The real answer to why babies look between their legs like that, though, is because it’s fun.
