"What's that?" you ask about sound outside. "It's just a car driving by," dad says. "What's that?" you say again. "It's the sound of the cat, asking for her dinner," I answer.
You ask a lot of questions using this "what's that?" format. I wondered where you got it from and then I found myself, the other day saying, "what's that?" directed toward a mysterious sound below the window. (It was just a bush, brushing up against the siding.)
I love your "what's that" and know you will soon add "why" to your repertoire. These questions make things more interesting -- they help our conversation flow. It's nice to give you words for things; I enjoy the clarification.
Tonight at sleep time, after you gave your love, you shuffled to your bed and climbed in. I watched you arrange yourself, finding it difficult not to help you in some way. I'm glad you still need me to tuck the blankets around you. Every day, a new part of your independent life is revealed -- what's that?
