Up and more, That's all

My nephew is taking his time learning to speak, so he doesn't say too much yet, though he has his own versions of lots of words--like "help," and "apple," and "birthday," which don't sound anything like the actual words and therefore can only be interpreted by his family.  But for months, he's been saying 2 things very clearly.  He says "up" out loud, and he knows how to say "more" in sign language.

Up and more.  That's all.  It doesn't seem like much, but my nephew has taught me that these words have so many shades of meaning.  You want to be closer to something, or see something?  Up.  You want to keep eating, or you want to see something funny again?  More. You want to gain the perspective of those around you?  Up.  You don't want to leave the people you're with?  More.  You just want to be held?  Up.  You just want to be loved?
