That's right it's getting close to Christmas time. Just found this on Lausanne Mom, how to mail letters to Santa.
Apparently you just address an envelope to “Santa Claus, North Pole" or "Père Noël, Pôle Nord” and drop it off in the Swiss Post. It seems many kids even get a little present back. We are mailing our letters to the Swiss Santa tomorrow, so will keep you posted on what the kids get back in the mail. Fun idea.
