This hula-hooped hand belongs to the little one. He recently discovered that they fit on your fingers, and not loves to slip them on and wave his hands around. Of course, you then have to give him another one to actually eat, because you couldn't possibly eat a hula-hoop off your finger could you? Or at least not until all the rest had gone :-)
"Some, Some" is the way the Little One asks for what ever edible thing you're holding and he wants. And I guess it does make sense. After all, how else would you answer the question "would you like some?".
