In each Posada, children are given candles and a board, with painted clay figures of Mary riding on a donkey and Joseph, to process around the streets with. They call at the houses of friends and neighbors and sing a song at each home. The song they sing is about Joseph and Mary asking for a room in the house. But the children are told that there is no room in the house and that they must go away. Eventually they are told there is room and are welcomed in! When the children go into the house they say prayers of thanks and then they have a party with food, games and fireworks.
Each night a different house holds the Posada party. At the final Posada, on Christmas Eve, a manger and figures of shepherds are put on to the board. When the Posada house has been found, a baby Jesus is put into the manger and then families go to a midnight Church service. After the Church service there are more fireworks to celebrate the start of Christmas.
One game that is often played at Posada parties is piñata. A piñata is a decorated clay or papier-mâché jar filled with sweets and hung from the ceiling or tree branch. The piñata is often decorated something like a ball with seven peaks around it. The peaks or spikes represent the 'seven deadly sins'. Piñata's can also be in the form of an animal or bird (such as a donkey). To play the game, children are blind-folded and take it in turns to hit the piñata with a stick until it splits open and the sweets pour out. Then the children rush to pick up as many sweets as they can!
Poinsettia flowers, also known as nochebuena flowers, are also very popular in Mexico. We watched this short story by one of my favorite authors, Tomie DePaola, titled The Legend of the Poinsettia.
