The son had some more "words" with his dad about how he is not paralyzed and needs to at least try to do some things for himself. I.e. use the urinal. Night after night, hubby has gotten up for the bathroom calls. Some times this means every 10 to 30 minutes.
Hubby has been inventing all kinds of things that might be helpful. One was a modified urinal. Amazing what one can do with a heat gun and a vinegar jug, AND sufficient motivation.
Then yesterday, he built a stanchion so that his dad could pull himself up in the bed so he could use his modified urinal. Evidently, that really helped the problem. We can only hope and pray that this night time peacefulness will continue!
