Speaking of bones, they have nearly a hundred more than you do. Around three hundred separate pieces that slowly fuse together as they grow. And when they cry about it? Completely dry eyes. Tear ducts don't fully open for weeks. They aren't tiny humans; they are entirely different biological machines.
