Flat Nappies are where cloth nappies first started – a simple terry or flannelette square. These still form the basis of many cloth nappy stashes. They are quick to dry and remain the cheapest way to cloth nappy your baby. Prefolds are the next step up from flat nappies. They are a rectangular shape with three panels, the middle panel is made up with more layers for extra absorbency in the wetzone whilst eliminating tricky folding. Prefolds are a great economical option for cloth nappying your baby and are often used for the newborn stage where frequent changes are required. Both Flats and Prefolds require a waterproof cover over the top.
