Covers/wraps: Covers and wraps give a closer fit, as they are adjustable. This makes them ideal for both chubby and skinny babies. These often look somewhat like diapers, and they are usually fastened by either aplix or snaps. These may be made of assorted materials, ranging from polyurethane laminate cotton fabrics, fleece, polar fleece, wool or felted wool. There are many reputable brands of covers/wraps.
Wool Soakers: Wool soakers are made of wool. This is a wonderful fabric for nighttime diapering. These covers are designed to become wet on the inside, thus pulling the moisture away from the baby. As the air flows through this natural fabric, it allows the moisture to dry, and baby to stay drier, thus making the ideal nighttime diapering cover. These covers do require a little extra care.
