Have only recently started to scrape poo from sposies, cos only recently did DS start doing any that were scrapeable. I keep a roll of cheap paper towel with my nappy bits and bobs and drop that in the loo for flushing next time an adult uses the loo. Reduces water for that nappy change.
For cloths I do the same where I can, but if it's too runny, it goes down the laundry sink...which is the same as the loo cos all that water goes to the same place.
I've been using the Reject shop bags, too, but it makes me uneasy cos it's non-biodegradable after non-biodegradable! I really to try to only use sposies at night, and now that I have some pocket nappies, I use them for going out instead.
Toying with the notion of getting the Moltex ones for night because that's only one nappy I have to pull apart to compost. I can deal with that!
