30. This rare charm is a wonderful rendition of the Della Robbia infant in a famed glazed terracotta medallion decorating the loggia at the front of the Hospital of the Holy Innocents (Ospedale degli Innocenti), a children's orphanage in Florence. There was a door in the orphanage with a special rotating horizontal wheel that brought the baby into the building without the parent being seen. This allowed people to leave their babies, anonymously, to be cared for by the orphanage. This system was in operation until the hospital's closure in 1875. The infant in swaddling, as it is also known, was chosen by the Academy of Pediatrics (AAP) as its symbol in the early 1930s and has since become the international symbol of pediatrics.
