Prefolds are as basic as you can get with cloth diapering. It’s a staple for most moms that use cloth diapers. Regardless of the system you have, you will always need prefolds at least during the newborn stage, or even just for back up. Flats are the most versatile cloth diaper style and the easiest to use when traveling because of the fact that they are very trim, they’re easy to wash and dry fast.
