Blowing Raspberries

I think that's what it is called when babies blow bubbles through their lips. Caterpillar Girl now spends several minutes at a time blowing raspberries, making that plbbbt sound, until her face is all wet. It's immensely funny to watch. She loves it even more than cooing these days. When I talk to her, she spits at me in response. Then smiles her widest when I laugh at her in return--an interchange that probably says more than all the peace talks in the Middle East.
