What did ancient people use as nappies?
Ancient diapers consisted of peat moss and grasses placed into animal skins and cloth to absorb urine. In Japan, parents used old kimonos that were fashioned into diapers, and in China, young children had slits made in their underpants and shorts to allow them to go as needed
In Europe in the Middle Ages, babies were swaddled in long, narrow bands of linen, hemp, or wool. The groin was sometimes left unwrapped so that absorbent "buttock clothes" of flannel or linen could be tucked underneath.
