Hey hey hey, what's this? what's this?

Those of you who have known me for a long time - do I walk around constantly saying "Hey, what's this?"? Because this is how Eva asks about EVERYTHING! It sounds really funny because there is such genuine wonder in her voice : "hey hey hey what's this?" as she points to a clump of dirt on the ground. "Hey hey hey what's this?" (a leaf) "Hey hey hey" (fluff from the sycamore tree). Once in a while her "hey, hey, hey" gets frantic and that is how you know something is really happening (a squirrel digging at our roof that only Eva could see because she was laying down on the changing table). I have come to really love this "hey hey hey" because it comes pretty close to expressing the wonder of a million of little things that Eva has never seen before and I take for granted. Like a star on the cover for the water department's man hole. Or the balls on sycamore trees in the spring (the ones that are making flufff now) or light reflecting off of my cup of tea. But do let me know if I say "hey, what's this?" a lot because then I could take credit for teaching her this expression.
