Separate bed covers.
I was just reading a blog where another mom was complaining about her husband being a covers hog. My husband and I have had separate comforters since before we were married. We now have a very big bed and we each have our own queen sized comforter but before that they were just full sized.
We still snuggle together while falling asleep but no one (me) wakes up shivering in the middle of he night because "someone who shall remain nameless" (him) has rolled himself up in the covers again.
I suspect this is why we are still so blissfully in love...
Just my bit of advice for a Monday morning.
