We used towels and flipped over the mattress. Next time we do it, I'm thinking about maybe getting diapers. Because like I said I would like to try it again sometime.
Well, I love ABU. They're pretty inexpensive for ABDL-designed diapers and come in a large variety of styles. I've tried the SDKs, Preschools, and Lavenders and I loved them all. Of course, if price is not an issue, go with Rearz, SUPER thick and SUPER absorbent!
