A flat diaper is a simple, rectangular piece of fabric used for diapering infants. Typically made from materials like cotton or bamboo, it requires folding to fit snugly around a baby. Flat diapers are versatile and can be adjusted to different sizes, making them suitable for newborns and older babies alike. These diapers are often secured with pins, clips, or a diaper cover. They are easy to wash and dry quickly, making them a popular choice for eco-conscious parents. Flat diapers are part of the broader category of cloth diapers, which includes other styles like fitted diapers and pocket diapers.
