Hello I have 18 newborn AIO diapers and I want to make up the rest of my nb stash with prefolds and covers GMD prefolds and blueberry nb coveralls. I want to be able to wipe down and reuse the covers a few times before washing if it's only pee so my question is how many covers do I need to make up the rest of my newborn stash and how many prefolds should I have if I am switching them out through the day? TIA the Prefolds come in packs of 12 how many should I get?
