AC Clapping on her own

We realized the other night that if you ask AnnCarter to clap, she knows what you're asking her to do and will start clapping without being shown.  I was amazed!  She is definitely picking up on language.  She's also started to wave a bit this week--I will try to catch that on video soon.  She doesn't do it all the time, but she's connecting more and more when you're supposed to do it and will often start waving if someone new enters the room.  She is growing fast!
