I am so very sorry you are going through this. I believe it is much more difficult for older couples who have been together a lifetime. Some ideas that might help: 1) I bought a toilet chair that can be placed by the bed so there’s no need to wander lost looking for the bathroom. It’s portable & can be moved out of the way during the day. 2) I installed light switch plate covers (from Amazon) so my husband can find the switch to turn the bathroom light on. (One bathroom is just 6’ from the bed but he still needs directions to find it.) I also found motion-sensor toilet bowl lights (also Amazon). They detect entry into the bathroom & light up the inside of the toilet bowl. They have a flexible arm to fit over edge of bowl. They are easy to keep clean. I take them off in the morning & wipe them down. 3) plug in and/or motion detector night lights (as someone has suggested). Hope these ideas help ease things a bit. This group is a great resource that you can check with at any time.
