National Geographic has this short article about a festival during which people line their babies up to have men jump over them.

El Salto del Colacho, Spanish for “the devil’s jump,” is said to cleanse the babies of the “original sin” of conception and protect them from illness. The babies, born in the last twelve months, are dressed in their best clothes and laid on mattresses in the streets. Men dressed as devils, often carrying whips and truncheons, jump over babies by the dozen.
