Well, when I left Ella this is what she looked like:
My daughter had the nerve to roll over for the first time without letting me watch! Well, you can imagine my shock and surprise. (I think she may have been confused as to why I was yelling in delight.) So, I put her back on her belly in hopes of a repeat performance. No luck, yet. However, I can tell you right now that she will be spending the bulk of her day on her tummy.
