I kind of figured she'd pick up waving soon, after all, on the cruise EVERYONE was waving at Avery. Sure enough, when I walked in to pick her up yesterday she turned (in a walker) looked up, grinned, and waved. She often has her little hands moving, moving, moving when she gets excited. When she's doing this her fingers all go like she's plotting some evil plan. Instead this was nearly like the queen waving to me - fingers straight and the whole hand moving. I'm told she was practicing it all day. I'm trying to catch it on video.
She has continued saying Mama, and periodically throwing in what I believe is Baby after.
