I gave 'em a try, and I DID find them to be a whole lot more work. You've got to dump the diaper contents, rinse the diaper, and then you've gotta have a place to store the dirty diapers -- when we had our children, we lived in such a small house that this was a real issue for us. And while I had babies, an extra load every other day WAS real work for me.
Also, my girls CONSTANTLY had a leaky cloth diaper (yes, I had some of the new-fangled type), so I was changing and washing their clothes more often.
My mom didn't have the option of disposable diapers, but she tells me that back then everyone had a diaper service that delivered fresh diapers to your door. And my mom certainly wasn't wealthy when I was born. What she DID have -- and what was typical for her generation -- was several live-in relatives, so the work was divided.
I wonder if this is a kill-bacteria thing rather than a neatness issue. You know you have to use HOT HOT water for washing diapers, and that's not cheap.
