First off, I didn't know they made reusable wipes. I happened to stumble on these in the store looking for barrettes to keep small one's hair out of her face. They have been wonderful.
Small one is now potty trained, but this made it super easy to clean up any accidents during that process. They also worked as wipes to get her to practice with before switching to toilet paper. As an added bonus? They're super soft and great for cleaning glasses. I'm sure as time goes on, I will continue to find uses for these things.
When I was little, we used old, cut-up reusable diapers to clean our glasses, because they wouldn't scratch the lenses. These work just as well, if not better, and they don't get lost like the little tiny freaking screen cleaner/ glasses cleaner cloths that you're expected to be able to hold onto. At roughly $2.50 for 12, you can't beat that!
