Two or Five?

So many people have told me that Elyse doesn't look or act like a typical two year old. I most often shrug my shoulders and say, "Yeah" not really thinking about it. Except I saw it this week. While she had her backpack on and just about to walk out the door to go to school I looked at her and instantly visioned her being in kindergarten.
For those of you who know Elyse, what do you think, two or five?
