All-In-One Diapers- AIO cloth diapers are just as they sound- one piece, all in one. These are the most similar to disposables. They require no stuffing, no wraps, and no pinning. One drawback to the AIO is that they have a longer drying time due to the several layers of thickness. These are a great option for childcare providers though, as they are the simplest diaper to use.
