Try and let her make the final decision Fred or it will always be your fault. She probably knows herself that this would be the best outcome but just won't admit it yet.
My mother fought tooth and nail just to get her to use a walker. Thought WW3 was about to start but she finally came around to it and loved it..
I guess it's like admitting defeat in a way.
Maybe one of your kids could use a car.
Same deal with the FIL except the war is still active. The walker is standing there in the corner and he moves around from counter to chair to wall to doorway. Maybe he uses it when we’re not there. Just being a butt head.
