We used to play sleeping games, too.

Now, we tell Mr W that he hurts our feelings when he does this. It works much better than anything else we can say.

He is so sensitive that once we tell him something like this, he will burst into tears and tell us "It will be ok." and then we have to spend 10 minutes calming HIM down.

So we use it sparingly.

He is a very light sleeper and recently had issues sleeping in his room, so I slept in there and sure enough, the heater in the attic makes loud noises and his ceiling fan has developed a bad bearing.
