I had lepidopterophobia for years as a kid. I was utterly terrified of butterflies to the point where I'd scream and cry whenever I saw one. One time, when I was little, my parents took me to a butterfly sanctuary. They thought me seeing them and being around them would make my phobia go away. It went about as well as you'd expect.
I was wondering if these sorts of things were common among people who had phobias as children.
