I am new here. My mom moved in a few months ago. She is 88 and has dementia. She sleeps well at night for which I am grateful. She goes to bed around 8-8:30 and sometimes sleeps until almost noon. A few times this week, I peeked in around 10 - 11. She was in the bathroom so I figured I would start making her breakfast, but when I checked again, she had gone back to bed. Is this normal?
