My suggestion is to leave her alone in the mornings to the extent that you can. Buy a backscratcher and don't ask your mother to scratch your back, especially right after you have told her she was acting goofy. Use a little common sense regarding your mother and her husband, and don't do anything she feels is inappropriate behavior in our out of his presence.
