I've got a reasonably large collection of reusables, mostly second (or third, or fourth) hand. Far too many to use, because if I used them all before washing, they wouldn't all fit in the machine in one go! But I'd never get that far, because I can't actually fit that many into the two nappy buckets I've got. One upstairs in the bedroom en suite where most nappy changes happen, and one downstairs as 'overflow'/nappy taken off before bathtime. They're normal-sized nappy buckets (one is One Life, the other's a Mothercare smart nappy bucket) and I really have to force the lid down on them after about 36 hours. So the room smells of dirty nappies, and I know I could go for longer before washing, but have nowhere else to store the stinky ones.
What do other people with, ahem, generous nappy stashes do? Do you just have an industrial-scale dustbin with a lid?
