When I taught kindergarten, the mistletoe would be one of the decorations I'd put up along with a little Christmas tree, home made stockings for each student, and paper chains that my class worked on together.
I explained to them the meaning behind the mistletoe and how mommies and daddies could kiss each other if they stood under it at the same time. I told them that there would be no kissing in the classroom, so I came up with the idea that if two of them were to walk under it at the same time, then they could give each other a hug. Some times when the kids would come back to the classroom after recess, I would see two of them realize that they had just walked under the mistletoe, then stop to give each other a hug. It was too cute!
Just thought you'd enjoy one of my favorite memories of Christmas....happy decorating (and don't forget the mistletoe this year!:)
