Names for things, names for people

Oliver is now starting to realize that there are two different languages in his life, I think. For a while now, he will call things by two names if he knows them both and especially if he really wants something: “barco, barco, boat, boat” when he wants to watch his “on the go” Baby Einstein video, for example. His vovó/grandmother now routinely asks him, “how do say that in English” and he will answer.
He will also now successully answer questions about proper names from relational names: What is mamãe‘s/mommy’s name? Leda. What is papai‘s/daddy’s name? John Norvell. What is vovó’s name? Dona Maria (because he’s heard me call her that). What is the neném‘s/baby’s name? Oliver!
