Limit the amount of fluid they have at night. It may be easier for them to have a portable commode next to their bed, so they do not have to search their home or rush to the bathroom. Also, try using an overnight incontinence product like an underpad sheet or disposable absorbent underwear. If your loved one isn't used to the idea of sleeping with an incontinence product, place the underpad sheet underneath the bed sheets to cut down on having urine soak into their mattress.
