"Your timer's beeping, Mommy!"

Several days ago I was down the hall in a bedroom and heard my timer in the kitchen going off. I didn't go immediately to turn it off, and heard Katherine say "Your timer's beeping, Mommy!" This is the first time I remember her addressing me as "Mommy". She would talk about me, or to me, but never call for me by my name, or use my name in asking me something. It's cute - now she'll tack on "Mommy" or "Daddy" to many of her "running commentary on life" comments, if one of us is around, as if to share her comments with us rather than talking to herself (or at least before, we had to guess as to which it was - talking to us or to herself). Just one more little step of verbal progress (which, we thank the Lord, is not lacking!).
