Here is an extract from 'The Modern Home Doctor' written by physicians in the UK in 1935.
Nice old, soft bits of good Turkish towelling, properly washed, will make the softest of diaper coverings, inside which specially absorbent napkins (diapers), see below at 1A, soft, light, and easily washed, are contained.
In the 1930s, Robinsons of Chesterfield had what were labeled "Destroyable Babies Napkins" listed in their catalogue for the wholesale market.
In 1944, Hugo Drangel of the Swedish paper company Pauliström suggested a conceptual design which would entail the placing of sheets of paper tissue (cellulose wadding) inside the cloth diaper and rubber pants.
When diapers become soiled, they require changing, generally by a second person such as a parent or caregiver.
Failure to change a diaper on a sufficiently regular basis can result in skin problems around the area covered by the nappy.
The constant problem to be overcome was diaper rash, and the infection thereof.
