Lyn's sleep pattern has definitely changed. She still goes to bed early in the evening. Frequently, 5pm is beyond her ability to get beyond.
She's now getting up about 5 hours later. She'll be up for 30 minutes to an hour. She'll come out of her room and look for Mom and Nikka, often saying she heard or saw something that woke her up. We suspect she's still hallucinating at night. She'll sit in her chair and watch tv if it is still on. After a bit, she'll start to fade again and Mom can redirect her to bed. Mom will then go to bed herself.
A couple of hours later, Lyn is up again. This time, she finds the house dark and works her way to Mom's room. She'll ask Mom if she can get in bed with her. Mom will hold the blanket up so Lyn can slide in beside her. They'll both fall back to sleep. Lyn snores terribly and Mom doesn't quite sleep as well as could be hoped. If Mom can't fall asleep, she won't get up or relocate. If she stirs, then Lyn's up and up for good.
By six, Lyn's up and ready for the day. She'll get up and let Nikka out. If Mom doesn't get up, Lyn will come and talk to her every few minutes, eventually telling her it is time to get up. It may be 6:30 at that point.
The sleep is definitely interrupted. There's no getting Lyn to nap unless she's sick and napping during the day will increase her nighttime wakefulness.. She's sleeping less than she was a few months ago but this is just one of the transitions in Alzheimer's.
This is an expected and unsurprising change. At this point, we're thankful that she's not yet wandering. However, it is time to get the black rugs out and install a couple of baby proofing measures like the door knob covers which will prevent her from going out the door unsupervised.
