she is waving

I just taught Violet to wave hi when we were in the bathroom together. I gave her an opportunity to go potty earlier in the day but she decided she didn't have to go, so I started waving "hi and bye" and she copied me. Just a few minutes ago, I asked Dave if he wanted to put her down for bed and he said OK, so I handed Violet to him and I said "bye Violet!" and waved my hand. She looked at me, raised her hand and started waving it in the air. I love how she's catching on to so many things lately.
