I forgot to add, my newborn stash is all mostly used. My one size stash is a mix of used and new. I have new Alvas and they are perfectly fine. Mama koala is pretty much the same as Alva, and so is Nora’s nursery, all work well for us. I do also have LPOs (I like them probably the most but I don’t like their included inserts) and grovia ones (we use these exclusively for overnight) and grovia hybrids (not my favorite, washing poop out of these hasn’t been fun at all and I tend to just wash the whole diaper after one use instead of just replacing the inner peed on one)
