Questioning Cooper

Cooper has been able to answer yes/no questions, animal sounds, how old are you, what do you want to eat, etc for awhile, but for the first time he answered a non-yes/no question about what happened in the past.

I asked him, "What did you have for dinner tonight?". He answered, "Lulu's house". I asked, "What did you eat?". He answered, "Spaghetti with covered cheese". (this means spaghetti covered in cheese)

Not all that interesting a conversation, but I have a feeling it is the beginning of something. He is about to start pre-school so I am curious how much he will come home and tell me about.
