My DD is 20mo and in the last month has become scared of the hoover. We have 2 hoovers one that charges on the wall and then a Henry hoover. It's too the point now where the one on the wall has to be hidden behind the curtain and the Henry has a sheet over it. She won't even go in the room if she can see it and cries her eyes out. Is there anything I can do to help her get over this fear? Any advice would be great.
