Sarah and Candace have a queen size bed that they share. Earlier this week, while Tom was out of town, they slept with me in our king sized bed... but they still ended up like this:
Like puppies in a basket
They sleep like this pretty much every night. When they had twin beds, one would crawl in with the other so they could snuggle up together. This is how they like to sleep when snuggling with the parental units at night, too. Which isn't particularly restful, but it sure is sweet. :)
