A small person's big identity question

I'm not sure who my daughter is. Neither is she.

In a sense, that is. Of course, my wife and I know our nearly 3-year-old better than we know anyone, or anyone knows her. And Lily knows herself best of all.

But we're at a loss in terms of her identity - a question that has only recently started to emerge, as she reaches an age where she understands some distinctions between languages, locations and nationalities.
