What can I do to stop this behavior? I feel like I'm reinforcing it by always answering and trying to do what she wants, especially for me to be in the same room with her. I leave the room and this calling me starts. It's hard to deal with as obviously I have other things to take care of also. Suggestions?
Where are you and the rest of the family?
Is she isolated in her room?
I suggest that you move the bed to the living room or other area where she can be part of the family.
This might solve a few problems.
She may not call out as much since she is with people.
If she does call out you do not have to walk as far to get to her.
This may mean you have to change some furniture around but it just might make your life a bit easier.
Can you move her to a recliner during the day in a central room like the TV room?
It may give her a sense of being more part of the family instead of being isolated to her bedroom. Find an old movie or the elderly seem to like game shows.
You can get her wifi headphones for volume control for the TV.
I find music is a wonderful distraction if you play songs from her era.
Maybe give her a box of old photos to go through?
Lastly, if finances allow, hire a local person to stay with her for a couple of hours. This will give you some freedom and peace of mind and give her the companionship she is seeking. Best of luck to you.
It sounds harsh to not go running every time she calls for her, but that's how it has to be and she'll get used it.
