It's hard for me to say exactly where DD was at 12 mos, since everything seemed to be happening so fast, but I'd say two word sentences sounds about right. We never did any kind of word count, again because everything seemed to be evolving so quickly, any such count would rendered inaccurate almost as soon as it was completed.

I know she had more than three words by the time she was 6 mos, because that was when we originally planned to start working on baby signs, and we decided that since she already knew how to say a very basic word for everything she needed, we'd skip it.
