I have always liked the phrase "took to her bed." I know that it usually is used describing someone who is depressed, or ill, but I love the chance to take to my bed!
I have always loved to nap, and my sweet husband always makes it possible when he can (I admit that I'm kinda cranky when I'm tired.)
When I had babies, my bed was my favorite place to nurse, so it was often a haven for me. It was easy to nurse a hungry baby, and then nap with the baby once they were full. As we've added babies, our bed is a comfortable place to snuggle with the kids and read books or watch TV.
We've shared a family bed since we've been parents, and while all the kids have their own beds, when they're small they spend a good portion of time in ours.
It's one of my favorite places in the house. Most evenings find the 3 kids and myself in bed while I read bedtime stories (we're currently reading The Horse and His Boy ) before they head off to their own beds.
We had always had a queen sized bed, until we were expecting Lydia and we finally bumped up to a kind size mattress. Bo insisted for years that a king size bed wouldn't fit in our bedroom -- but it fits just fine! We did do some online research before choosing our new mattress, and have slept soundly on it ever since!
