What prevention should we use to have elder not urinating on floor or bed at nighttime?

Is your Mom urinating on the bathroom floor while she is trying to pull down everything?

I had that problem with both my parents. It's almost like they wait too long before they go. I bought bath towels and had them cut in two. Had them shaped to fit around the toilet floor. Then I bought rugs that would absorb any urine and also easy to wash. I was always worried they would slip in the bathroom.

In the bedroom I used runners and occasionally had to wash them. I use plastic bed covers on their beds I buy at Wal-Mart. I buy disposable pads at Sam's, fold a sheet to a quarter over the pad then may put another disposable over that. I usually only have to change those three items and not the whole bed. That's only when Dad also has periods where he takes everything off at night.

Another thing, not all pull ups are created equal. Some are better than others. After trying different brands, I stayed with a generic brand called "Reliance" for men. I was so happy with them, I use them for Mom too. They are great when they are left on.

I leave extra diapers and clothes in the bathroom. It took awhile but they finally felt comfortable urinating in the diaper If they needed to.

Hope this helps!

An incontinence pull up can catch any accidents but a bedside commode might also be of help if the problem involves her not having time to make it to the bathroom.

Have you thought of using bed or floor pads? Most are disposable and some are washable.
Here is what I used.
Water proof matress cover to protect it. A royal pain to wash and dry and untangle.
I found the washable pads. Loved them even though I might have to do two or three light loads a day. They worked on the flooring (carpeted) as well. wwork on sofas and chairs.
Loved them so much I bought a second set.
She still wore the protective underwear though.
The brand I used is peapodmats. Other brands are available out there.

Your mother needs to wear adult incontinence briefs such as Depend or Prevail. Do NOT call them “diapers” as this is insulting to the wearer and brings to mind a baby. There are many brands and sizes of waterproof bed under-pads you can use on the bed, including disposables. Be careful what you use on the floor as it can be slippery. If you have carpeting in the room, remove it and replace with tile you can mop and disinfect. Restrict her fluids after about 3PM. No coffee or tea after then.
