"Vidomégon" in Benin means, in fon language, "children in foster care". An ancient tradition meant that the children of the poor families of the countryside went to study at the rich ones or with relatives in the city, but in recent decades this habit has often turned into a sort of child traffic for labor. About 400 girls and children are living in the Great Market of Dantopka in Cotonou. Sister Maria Antonietta Marchese and the Salesian Sisters have for about twenty years created an house in the market, being now a point of reference for combating the exploitation of child labor throughout all the country; in these years they have created an important network with schools and reception, in an attempt to monitor and recover at school, together with specific State structures such as the Police of Minors, psychologists and teachers, as many children as possible.
