One of the things I found that was most helpful with incontinence was a pad that covers the entire bed - fits most half beds and hospital beds. This new pad - I purchased four - keeps the sheets from getting wet as well as the mattress pad. I also keep another pad under the sheet to protect the mattress. Another thing that has helped is that I trained myself to hear him during the night and to get the urinal. This took a while but it has helped.
Another important thing I learned recently is just how important it is to take care of yourself. I know we all say this but I didn't pay attention to myself until it was nearly too late and was rushed to the hospital with sepsis. Now - four weeks later - my doctor still won't let me bring my Tom home from the assisted living. Says I need at least another 3 weeks to build my strength up. Don't let this happen to you. After living under this strain for years, it takes on a long time to come back from a major illness. The doc told me that another 24 hours without antibiotics and I would not have lived. That's a scary thing to hear to PLEASE, all caregivers, take care of yourself.
