We also are very into using signs and words to communicate our wants and needs and some of our most frequently used include:
Signs & Words - more, milk, please, bath, all done, play, my turn (mine), your turn, thank you, Papa, Mama, book, yes, no, kitty, dog, ball. Words only - back, belly, eyes, nose, mouth, ears, arm, fingers, toes.
These are our favorite shirts at the moment and we get very excited when we can wear them and then can pretend we are a kitty or puppy!
