Child sacrifice is when people take children and kill them as a way to please their gods or spirits. Some people believe that sacrificing a child will bring good luck or make their wishes come true. This is a very bad thing to do because it hurts innocent children and doesn't actually make anything better. It is against the law and very dangerous for anyone who tries to do it. Child sacrifice has happened in some places in the past, but most people today know that it is very wrong and would never even think about doing it.
