PLEASE!!!

I realized something tonight, every time I tell Emma to say please she rubs her chest while she says please. After seeing her do this time and time again I got to wondering maybe that is the sign for please. I googled it and it is. That is the second time she has signed something and I had no idea what she was doing. I need to get up to date on my signs so I can keep up with my 1 year old. That's sad!
