Da, da?

Troy has started to say, "da, da" less as a statement and more like a question.  I'm not sure if he's asking about something in the room, but doesn't know the words for it, so he's just asking me a general question and hoping that I'm smart enough to figure it out.  Or if he's simply trying to get my attention so he can point something out to me.  Either way, about three dozen times a day, I hear, "da, da?"  And I always reply with, "yes, baby?"  My wife thinks both questions are adorable.
