She ends up peeing everywhere - her clothes, the carpet, the mattress, etc. Although she is in assisted living, my cousin ends up doing many many loads of urine-soaked laundry. How can we "re-train" her to use the toilet properly? My aunt keeps saying that my cousin "doesn't understand" but she cannot explain why she is doing this. We don't want to shame her, but this is causing SO much unpleasant work for my cousin.
