90 year old refuses to use walker or cane....stumbles all over the place. Anyone else dealt with this?

My 91 yr Mom didn't want to use hers either. We got her a Medical Alert necklace..

I'm sorry your grandmother is doing this. My mother-in-law kept doing the same thing. We could not get her to use the walker until she finally hurt herself bad enough that she was finally convinced she needed it. So unfortunately, there's probably not a lot you can do to change your grandmother's mind until she decides to use it herself. But keep reminding her - and hopefully she will accept it sooner rather than later. And if she falls and hurts herself badly - it wont be your fault. You have tried to get her to comply - and that's all you can to is try. But you won't be held liable unless there's good reason to indicate you may have "caused" her to fall. Good luck!!
