Here is a video of Lainey talking and signing. The words you will hear her say are "yeah" "I don't" for don't want, "thank you" and "more" (sounds like moy). The signs are more, milk (which she also uses for want), water, thank you and all done. It was easier to understand what she was saying in real life, when I watched the video it didn't seem to capture her words very clearly.
She is a chatterbox and parrots a lot of what we say. Her longest sentence is "here you go, mommy" (which comes out "here go, mommy")
