Waving

About a week ago we were at the grocery store and on our way out one of the people working at the store waved to Abby and said good-bye. Then I heard her say, "Oh, your waving back!" Really? I looked down and she was right, Abby was waving back. Before this there have been a couple instances where Abby's arm moves in a way that you might think it was waving, but I would say this was her first official wave. Since then she's been busy waving to everyone - visitors when they leave, strangers at the store, and all of us here at home. I just took her upstairs for her nap and said, "wave good-night to Anna"...and she did!
