She sounds like this: "two, three!" in a really high pitched voice which I think is what she thinks Adam and I sound like when we are trying to get her to say something.
Maybe we should all just get rid of "one". I mean, really, how many things in life would be so much better if there was more than one. Brownies, kittens, best friends...I'm sure there are others, but I'm blanking.
She can also say her "A, B, C's"...kinda. It sounds like this: "A, B, C, L, M, N, O, P," and sometimes she adds "Z" just to finish it off.
