I'm using compostible sposies (Moltex) which are fantastically absorbent and leave huggies for dead. I get them through a place in Bungendore that delivers - perhaps you can track some of them down.

I agree Sam about Baby Beehinds - the bamboo version seems to work for us and can be boosted to help big wetters get through a decent number of hours. Hester drenches the Baby beehind hemps though.
