Charlotte requested them, so here they are! Because this blog also posts as a note to Facebook and embedded YouTube videos don't show up there, I'll embed the videos and then hyperlink the video titles.
Video #1: Sosi being cute
Video #2: Sosi and Bobo fighting over toys
Video #3: Sosi almost rolls over! She actually did roll over right before I took this video, but of course she didn't repeat the trick after I got the camera rolling....
