We had a beloved giant MS patient in a nursing home where I worked; we used twinsized cotton sheets, folded just like a regular baby flat diaper, only giant. Kept a washer tub next to the bed, laundered nightly with simple salt/borax/soapflakes nondetergent, TOTALLY cured her skin breakdown! Rarely we'd put a cotton terrycloth towel tucked into the abdomen skin fold if she were starting that moist/fungal breakdown, (then change to low carbohydrate diet for a while, its related to sugars). the plain cotton, done lovingly, was no more effort than the shipments of plastic diaper and wipe supplies, when the work and expense of constant skin breakdown was factored in.
Later I adapted this to cloth diapering my babies. Saved us Tons Of Work. Instead of buying wipes, keep spray bottles of water and plain washcloths close by, launder with the diapers.
BUT NEVER USE "FABRIC SOFTENER", IT MAKES A BARRIER THAT WONT LET THE COTTON BE ABSORBENT! And if you use polarfleece for a moisture barrier over the diaper, never put that in the dryer, or it will lose it's moisture barrier.
I have heard discarded flannel sheets are being used in long term care facilities, too. But they'd have to be all cotton.
I think your pads are delightful. How would I buy some? Do you take orders?
