Whistle while you work

Last week your Mama and I thought we heard a whistling noise from you. With quizzical looks, we'd try and catch you doing it or ask you to whistle. You'd return our quizzical looks with your own. One day, I finally saw you do it. You completely taught yourself to whistle all by yourself. Just you. You didn't even know it was called whistling! Amazing kiddo. Love you. Papa.
