I can’t tell you how many times I had ended up with little to no blankets after sleeping 4 four hours. Eventually, spouse and I decided that we would get two full-size blankets for the bed so that we could each have one. This has prevented so many restless nights.
I’d have murdered someone years ago if I shared my blanket with my husband. We have a king bed, but like to be at opposite sides for sleeping. And I like to pull the edge of the blanket under my chin. Which means I’m pulling it off him and leaving him annoyed. No no, we each have our own and can cuddle the blanket all we want. And I can hide cats under my blankets.
