Who IS this little girl???

We finally had a day where it was not over 100 degrees here so I thought I'd take my "baby" for a little walk by the neighborhood ponds. I don't think we'd been down there since she could properly walk on her own because of the weather so I snapped a few (not great) pictures with my phone. As I looked at them later, I found myself wondering who on EARTH is this little girl in my pictures and where the h*@! did my baby go???
