I don't remember when I stopped, I had younger sibs so I must have had to pretend for a while. My DD was 5. She was in the bath and said to me, "The Easter Bunny isn't real, you do all those things." A moment of silent thinking. "And that means Santa is you, too." More thinking. Then she looks at me with huge tears in her eyes. " And that means the Tooth Fairy isn't real either." We never knew if was just all of them together that got her or if the Tooth Fairy was just that important to her
