Prefolds are a type of cloth diaper made from multiple layers of fabric, typically cotton, that are sewn together in a rectangular shape. They are designed to be folded and placed inside a diaper cover or used with a fastener, providing absorbency for babies. Prefolds come in various sizes to accommodate different ages and weights. These diapers are popular among parents for their affordability and ease of use. They can be washed and reused, making them an eco-friendly option compared to disposable diapers. Additionally, prefolds can be used as burp cloths or cleaning rags, adding to their versatility.
