My parents told me that a man and a woman had to do "something special" to make a baby. However, she didn't specify what this "something special" was, nor did I quite understand about pregnancy (I was very little). I'd also been told that babies came "from God" if you prayed for one, so I put the two together, and decided there must be some sort of special baby-creating prayer/ritual. I had vague mental images of my parents lighting candles and chanting until a baby spontaneously appeared in the room.
