I seem to have lost count.
Because I heat our home with wood, I will answer with a slightly more obscure geometric measure of my stash in terms of volume. In firewood terms, I have about two and a half cords of "snuggers" as we call them. (For you folks not firewood savvy, a cord is a stack of split firewood 4 feet by four feet by eight feet.) I have 2 closets and two linen closets devoted to storage.
As I use almost all brands, sizes and configurations of disposable diapers, pull-ups, belted protectors, boosters, pads and other incontinent products (many modified as boosters) in my day to day wear. There isn't a product that I don't/won't utilize.
Ok folks, get ready for the OCD part of the show.
My typical daytime/nighttime diaper configuration is typically the same if I am at home or traveling/driving long distances. It consists of layers of multiple diapers, pull-ups and modified boosters.
I use Clauss Titanium 8 1/2" shears (I own six pairs of these and highly recommend them) for all modifications and repurposing; (and as my Doe Bunny says) "....you have found ways to repurpose any commercially produced snugger in the most ingenious ways." Face it, for all practical purposes when you actually use a disposable diaper, typically 1/2 of it is not wet when you change. I shear off the used (wet) portion(s) and repurpose the remnant as a booster pad or insert.
My typical diaper system consists of at least 2 (NEW) briefs and 2 (New) pull-up. One comfortable brief (adult taped or velcro tabbed diaper) and one comfortable pull-up (adult disposable underwear) is left complete as manufactured, the others modified as boosters.
The second brief is modified by removing all surrounding plastic or cloth-like plastic on the outer edges of the fill/padding. I make no cuts or slits that would allow urine to pass through. This entire booster/liner is placed over the absorbent padding area of the main diaper, covering it entirely.
The first pull-up is left as manufactured with the exception of making slits over the entire outer surface of the padded area. The second pull up (typically a smaller size than I usually wear) is modified by cutting away the sides but leaving an intact 1 1/2" to 2" belt. V shaped slits are made with the shears about 1" apart over the entire outer surface to allow urine to pass through to the next layer.
Portions of my unused diaper remnants are edged, v-slitted and placed in successive layers (usually 2 layer or diaper thicknesses) over the first complete liner. The top layer is a complete 1/2 brief that has been edged and slitted.
After I secure the side tapes or tabs, I pull on up to 4 cotton briefs and a pair of plastic pants.
When I dress to go to the post office or into town, I use 3-4 pull-ups, one cotton brief and a pair of plastic pants under my jeans or pants, and usually go undetected.
