I've worked in care homes and took care of my grandpa, so here's some things. First off, remember grandma, although I'm sure wants you to move in, this is a big change! Aging is scary! So cut her some slack if she snaps at you.... it will happen. Also, the most important thing is she stays active. Physically ad mentally. Look into senior day activities, call you local senior center or church, if there is something that interests her, sign up for a class with her. Painting, cooking, bird watching. Helping keep the brain active helps with memory and quality of life. If you have a specific question you don't want to post you can pm me. I don't claim to be an expert, but I've worked in care homes, Alzheimer's homes and cared for my grandpa. It's not easy, but I'm glad I did it.
