You poor thing.....rolling wriggle bums are SO frustrating.

I now change Olivia on the floor (for safety) and the only thing that seems to keep her in one spot is the promise of being able to play with her hairbrush & blowing raspberries onto her tummy......I have to do that at every nappy change so that she is happy to lie on her back......shame it also means that she also gets her hands into my hair and pulls, or whacks me on the head with her little pink plastic hairbrush, plus the fact it takes a good 10 mins just for a simple nappy change..............

So no real advice really, but I do sympathise........
