I find anything pretty difficult so I get up around 5am and go on the computer, knit, enjoy the pretty backyard, etc. etc. my DH gets up around 9 as do the dogs and then it is business as usual. Some good, some not so good.
I get to sleep around 9-9:30 so I think I am getting enough sleep. Would like your comments please as I am new to this role. Thanks.
You don't mention your age, or the stage of your husband's dementia, how many dogs you have, whether they're puppies or adults, whether you have children, etc.
If you feel rested in the morning, then I'd say you're getting enough sleep. If not, consider changing your patterns.
You're wise to address this issue now before things get more complicated and hectic.
BTW, you can use a photo of your Labs as an avatar. I always enjoy seeing animals next to posts!
