What side do you sleep on?

Do you swap sides or stick to the same spot?

I sleep on the left at home, don't know why. Before we moved, I slept on the right. In our caravan, I sleep on the left because it's the easiest side to get out of if the kids wake during the night (right side is against the van wall). We don't swap.

Amuse me! I can't sleep in my bed tonight because it's too hot upstairs so we're sleeping on the couch downstairs and thinking about my comfy bed.
