Say My Name, Say My Name

Tommy and I were driving home from his grandparents tonight and he was talking about going home. We're trying to teach him about personal pronouns and not just to refer to himself in the third person (i.e., him saying "Tommy wants to go home"). Have you ever tried to teach someone how to use "I", "me", "you", and "my"? It's not easy. So I said "We're going to my house. What's my name?" (not sure why I asked that). He just busted out with a garbled form of "Krissie". Guess we're on a first name basis now.
