The fear of being covered with anything has probably diminished due to the morning routine. Rigby forgets how to mind when I make the bed. When I call her off of it, she crawls across it, makes herself longer and bigger, and somehow covers more and more of the bed with each, "Get down!". When this habit started, I would barely touch her with a sheet or pillow, and she'd spring off the bed with such a start. Now? Well, I can pile all the bedding on top of her, and she falls asleep! I think she's over that fear.
