One of my families uses cloth diapers and it is great! They provide a wet bag and stuff the liners into the diaper and have them ready to go for me. It is zero extra work compared to disposable. I don't flush anything unless it's a very solid poop and falls off the diaper easily. Just tell the family that you are happy to use disposables but that the diapers must be snapped up, lined, and anything else that needs to be done so they are ready to go. Tell them that you need a clean wet bag for everyday and that they must take the old one home. Tell them that you will out the dirty diapers in the wetbav but you don't clean them. Good luck with your interview!
