Bobby.

So, I'm Bobby. I guess it's better than "Daddy" or "Heidi" my two names up until about three days ago. Now I'm Bobby. Hayden says it with great excitement though, so I'll take it. Other words:

Shoes! (Always said with awe and excitement)
Hi
Off (to mean on, off or down)
Bye
Santa (always with a goofy grin)
Daddy
Bobby ;)
Heidi
Cheese! (Her favorite)
Hmmm (for hummus)
Doo Doo (for rooster)
GaGa (cracker and duck. Usually the context clues help with that one.)
NahNah All done - said with the sign language gesture for "all done")
NO! (how could I have forgotten that one?!)
BaBa (Bottle)
There are more I'm sure, and a lot of words that she'll copy (from "Apple" to "I love you")

First sentence?
Kev swears her first sentence was "You're still there!" while playing peek-a-boo. I heard it too, clear as day, but it's hard for me to think it was real. Kind of like the plant speaking in full sentences.
She said "I love you" with prompting
Tonight in the tub she was putting toys on her feet and I said, "You did that". She responded "I did that". Cool on a few levels, mostly because she changed "you" for "I". Still, I'm not sure I'm totally sold that she says all those things given that most of the time she speaks only fluent Muppet.
