I believe It used mainly on one thing every child when it is small believes, Santa Claus. Believe that he would enter the chimney with his reindeer, they would eat all the food that we put there. Other very common things are to believe in fairy tales especially in the Pinocchio tale that many parents use as an example for the child not to lie, but because his nose would grow. These are some of the things I believed when I was a kid.
