Another Big First!!!

Katelyn rolled over for the first time from her tummy to her back ALL BY HERSELF!!!!! She was on her playmat for some tummy time, and apparently decided she didn't like it anymore. So she wiggled around a bit and managed to get over onto her back. She was very surprised as to how this all happened. You can tell by the look on her face in the last shot.

Here I am on my mat.

What just happened????
