My dear MIL almost always had two babies in diapers. Total of 12 children. She said that she usually had 13 dozen diapers. They lived in an area with cold winters. She would hang diapers out on the barbed wire fences waiting for the temperature to rise so they would dry. My grandmother said her children never had yellow diapers even though she wsshed them in a creek. Some women would just dry the wet urine diapers and use them again. So glad for the disposable diapers I used on my babies.
