Little children putting stuff in their mouths has an immediate use. I discovered this with a child that lacked this stage of development. It's important to their eating. Babies learn to eat whatever they're fed. If they're fed spicy food, Thai hot, that's their normal. Being willing to taste/try anything makes this pretty easy. And, overall, babies are hard.
