When Adriana started using the sign for eyeglasses to refer to drinking glasses, Brian suggested making an effort to say "cup" instead of "glass," but since she isn't trying to wear drinking glasses or drink from my eyeglasses, I haven't bothered. She seems to understand that the same word works for more than one thing.
I often offer Adriana choices of things to snack on. "Do you want cheese or grapes?" I ask, and she signs her decision. A few days ago I asked her, "Do you want banana or edamame?"
"Mama," she signed.
"Banana or edamame?" I asked again.
"Mama," she signed, and pointed to the freezer.
I thought maybe I was wrong. I thought that she wasn't really saying "mama" for "edamame." But then at the park a couple of days later she pulled the little container of edamame out of the diaper bag and handed it to me to open.
"Mama beans, please," she signed. Oh well.
