Gonna be a grown-up

So, we get in the car after dance last night. Out of the blue McKenzie says, "I'm going to be a grown-up next year." I said, "Oh really." She said, "Yep, I'm going to be a little grown-up."

She then went on a mini dissertation about how at dance there were a lot of little grown-ups and big grown-ups and that next year she was going to be a little grown-up.

What happened to my toddler? Yesterday she was two going on three, today, she's two going on little grown-up.
