Rolling, rolling, rolling ... from front to back

 

I took this picture of Vivi looking very determined, thinking she was getting set to lift herself up, but no, she rolled herself over onto her back. And here's the evidence...

I'm not sure whether she meant to or not - she seemed a bit surprised at ending up on her back, but I rolled her back on to her tummy and she immediately rolled over onto her back again. This is the third (and fourth) time that I know she's rolled over - but the first caught on camera.
