Sims scooting over in bed?

I got it to work manually finally! I had my Sim already sleeping in one side, then queuing another sleep action from a click on the other side, then cancelling the sleep he was doing. He got out of the covers and scooted to the other side and got back in. I made him do it back and forth a few times. The key is to cancel the first sleep action after queuing another and after the Sim is asleep. So it's click bed>sleep/nap>wait until they're in the bed and asleep>click other side>sleep>cancel first sleep action. Sometimes it doesn't work and the second sleep action will just replace the first without them waking up in between, but just keep queuing another and cancelling the one in progress, it eventually works.

Edit- I figured out how to do it the normal way! Click the sweet spot. Too far towards the pillows, it won't work.. Too far towards the edge, it won't work.. Too far down, it won't work.. But so far, clicking that area around the center has worked every time.
