Holly This is normal for her to sleep and it's the process one takes when they are preparing to meet our maker. Just know that she knows your there and you are doing all you can. My grandma did the very same thing, slept so much and then one night she fell asleep and left us. I know that's hard, I know it is. But you are with her, she is with you, and nothing can ever replace that. She's lucky to have you in her final days.
