Lately, she's sort of overgeneralized the sign. Based on my studies of language development, I know that's common when children are learning language to overgeneralize, I just didn't really think about it in reference to SIGN language. But she now uses her sign for more when she wants something. Anything. This can get a bit tricky when you don't know exactly WHAT it is she wants. She has also started using the sign for "more" when she really means "help." I caught it on video. She's doing her sign for more (meaning help) when she can't get the last ring off the stacker and then again in order to get Mark to put the rings back on for her.
I love watching this little munchkin learn to communicate with us!!
