Gave Mom the day off. Do you think there's anything wrong with a day in bed resting?

I work long hours at the hospital, Mom was so tired yesterday when she had to get up for her caregiver at 0500..she was exhausted by the time I got home. I gave her today off to lay in bed or do what she wants. She knows I have to work tommorow and has to be up early. The caregiver is a fill in caregiver and doesn’t know her well,so I get Mom up and put her in her recliner when I have to work, so today she said can’t I just rest in bed today and I thought why not. So she has the day off to nap and rest. I asked her if she wanted to get up and she said no. A dr at the hospital told me dementia patients do need extra sleep because their brains work so hard to accomplish everyday tasks, so I’m giving her brain a day off...and mine...cause I’m exhausted. Do you think there’s anything wrong with a day in bed resting? She’s 81 with dementia eating and drinking great. Just tired. I’m a nurse and we get everyone up and moving, but I’m gonna let it slide and see if extra rest recharges her. Anyway I wish you all happy holidays and thank you for getting me through some tough situations this year...God Bless you all
