Born with a silver spoon in your mouth is an old saying. The spoon is the apostle spoon, or christening spoon, which is given to babies at their baptism by their godparents (this tradition has been practiced in Europe since the early 17th century and in the US since the early 18th).
The spoons often functioned as a status symbol and sign of the family’s wealth, with rich godparents traditionally giving the infant 12 spoons, usually silver, one for each apostle. Godparents who were not as well off give four spoons, one for each of the four Gospel writers. Godparents who couldn’t afford multiple spoons or silver usually just give just one spoon made of a non-precious metal.
The tradition of the apostle spoons is still practiced in some Roman Catholic families both in Europe and the US, the figurative silver spoon has taken on the negative connotation that a person attained their wealth through inheritance, not hard work.
