I have to think that washing ANYTHING in very hot water and bleach would take care of the sanitary question. I am not sure about the green efforts, though. My 3 children are grown...26, 28 and 31 "Way back then" I was thinking the same way, save money...save the planet. (Keep in mind the disposable diapers didn't even have elastic legs yet LOL!) My findings were this: To maintain the cloth diapers was alot of work. When they are wet, THEY ARE WET. Disposables draw the wetness away from that sweet little bottom...fewer changes, healthier bottom. The diaper pail is a pain in the you know what, not to mention unless you launder every day with bleach (not green or good for the planet or human fannies) it can tend to get a bit stinky. HOT water for the laundry takes energy to heat it (not green), don't forget the use of the water itself. Now, on to drying the diapers. Gas or electricity to heat the dryer (not green and is expensive) I hung them on the clothesline...ah...very sweet smelling, white, STIFF diapers for my sweetie's bottom. So...in the big picture, yes disposables do take up room in the landfill and they are not reusable, but the cloth diapers take time away from baby and alot of energy, yours and natural resources, to maintain them properly. Having done both, I would opt for the "greenest" disposable diapers available and spend that precious time with my sweetie, not laundering the diapers. Happy medium?
