As previously mentioned, Hailey is now at the stage where she tells us no all the time. She likes to say it in threes, as you can see here. She started saying "no" a month ago, when she couldn't quite pronounce it. She definitely can pronounce it now.
Luckily, "no" isn't the only word she's learned. "Cheese" has become her sixth word. Yes, she does like cheese, but she says it in the context of taking pictures. We don't tell her to "say cheese" when we take her picture, but somehow she came up with that.
Oh, and she's much better about smiling and looking at the camera now that she learned to say cheese. What a funny girl.
