This might be hard to describe. My biggest issue was urinary, not bowel while in the chair. Morning enemas mostly eliminated surprise accidents and while sitting, it was easier to not have a bowel movement. My issue was urine that spread to the butt or bottom of the diaper. This would be in contact with my skin and cause problems. Besides a good barrier cream and lots of baby powder, one solution was best for me. I only use plastic backed diapers, so that is what I recommend. I take a fresh diaper and cut it in half from front to back.(hamburger style) I could use both halves for this. I cut the wings off. I use it like a diaper double but upside-down in the back. Basically, lay out the whole diaper to be worn, take a half that you made and lay it over the butt or back region of the diaper but have iT with the absorbant side against the whole diaper absorbant side. Use baby powder to avoid sweat and sticking. Not cream. Pit diaper on as normal. The urine gets absorbed in front (for men) and travels to the rear as before. But now it is trapped between two diapers with the plastic side protecting the skin. I will create one with 2 cheap diapers and take a pic and post it in my photo album on here. Please let me know if I need to explain mire. This truly was a life changer for me. Nobody could help beyond damage control after a rash started. So I came up with this. I dunno if a modified version could be made for females. I imagine so.
