When ds7 was around 4 or 5, he asked me outright if the Easter Bunny was real. I suspected that he knew the truth, but was simply looking for confirmation. I told him that I would always tell him the truth, and would about this too, but that he had to be absolutely sure he WANTED the truth before he asked questions like this. He said that he wanted the truth, so I told him that the Easter Bunny was not a real. He broke out with "I KNEW it", and never looked back.
