She has occasionally said, "Ow," "Oh, oh," and, "Woah!" For one day she said, "More," but then that passed and she reverted to the sign.
Nothing but "Yeah" has been consistent until yesterday when she started saying, "No," as in, "Sissy, it will be time to get in the shower in five minutes,":
"Noooooooooo! Nooooooooooooo! Noooooooooo!"
I think that one might just stick.
