Eco friendly mostly. I was starting to get upset about thinking about all of her nappies ending up in landfill, and that eventually, mucky nappies would take over the world.
It's also in a massive part due to the fact that I kept finding nappy crystals on her bum, so I swore I'd never use them again. This was when she was about 2 months. I'd wanted to use cloth from the start, but I got absolutly no support from anyone other than my OH, and he (like me) had no idea where to start.
And the prettyness helps!
