My grandmother is 72 and has Alzheimer's. My mom, 42, and I, 23, take care of her, but we both work. My mom works 8-5 Monday through Friday. I work 11:30-6 Monday, Wednesday-Friday and 12:30-6 on Tuesdays. I know it's best to let her wake up on her own, but I have to make sure she is up and ready before I go to work so my mom can take her to her daughter's house for the afternoon (She lives with us at our house but can't stay on her own because we have pets). Lately, trying to wake her has become very difficult. She gets angry and yells. The other day, she slammed the bathroom door. I try to wake her very calmly and get her a cup of coffee made hoping that will help but it just hasn't. Any tips would be greatly appreciated.
