"No" and "Mine"

We're pretty sure Bridget is only 1-1/2 years old, but she sure is talking like a 2-year old. Bridget's new favorite word is "no", and she uses it a lot. Sometimes it's like a polite "no" in response to a question. But other times (or most of the time), it's a loud "NO!" with a shaking of the head. Her next favorite word is "mine", and she usually says it when she's with Jillian. Bridget has a pretty good idea of what's hers and what's Jillian's, and she's not afraid to vocalize it.
