Right now Sweetie has "more" and "all done" down and we are just beginning to work on "cup" and "help". She also has made up her own sign for up that I think is too funny. I must have moved my head to enunciate the word "up," so now she moves her head quickly down every-time she says "up" with her words, almost like she is saying half of "yes". Don't know where she got it from, but it helps her communicate so we'll keep it.
