Modern cloth diapers, while expensive, are very easy to use, and contain waste as well as disposable diapers. They pay for themselves in a reasonably short time and prevent all of this landfill waste.
Our daughter was premature, and we used disposables until she was large enough to move into the "one size" BumGenius diapers we got from our registry. I think we have ~20 of them, which means about $340 spent and a 3ish day supply without laundry. When we're done with them, though, we can resell them - yes, they have resale value.
The alternative we would be using is $0.21 each, so we'll break even after 245 or so days. Larger disposable diapers are more expensive so the savings will grow with time, not shrink, and the cloth ones are very adjustable.
