The Flat Diaper from Smart Bottoms is a single flat sheet of diapering fabric that folds to fit your baby and your routine. It is the oldest idea in cloth diapering, kept around because it works.Best for families who want fast-drying, endlessly foldable absorbency - as a diaper, a booster, or a burp-and-cleanup cloth. Three sizes - small, medium, and large - to grow with absorbency needs Folds flat for quick washing, fast drying, and thin storage Works as a standalone diaper with a cover or as a booster layer Simple one-piece construction with no elastic or snaps to wear out How big is each size?The small runs about 20 by 18 inches, the medium about 28 by 26, and the large about 35 by 32, with absorbency stepping up alongside the footprint.How do I fold a flat?Start simple: the pad fold is just repeated halving into a rectangle that lays into a cover. Angel folds and origami folds come later, once you are hooked.Why choose flats over shaped inserts?They wash clean easily, dry faster than almost anything shaped, and refold to boost wherever your child soaks hardest.Lay one into the Born Smart 2.0 for overnight boosts, and store the used ones in the Cloth Diaper Pail Liner. Everetts Place carries the full system.
