How old is he??

Ethan says "I'm twee" when asked how old he is. (He also holds up one finger and laughs.) Some days, I'm conviced he really is three. We've discovered that Ethan knows words like 'pirates' and 'slide', and speaks only in complete sentences. He's not just repeating sentences that he's heard. No. He understands what each word means and shuffles things around to say exactly what he wants to. Really, as he approaches two, (I KNOW! TWO!), learning so many new words is normal. But Ethan's understanding of sentence structure is a sure sign that Ethan is a product of his nerdy parents. (My extended family will probably point out that all babies born in the G family are super-smart. It's in the G genes. And John's would mention that they have their share of nerdy genes too.)
