A baby hatch or baby box is a place where people can leave babies, usually newborn, anonymously in a safe place to be found and cared for. This was common from the Middle Ages to the 18th and 19th centuries, when the device was known as a foundling wheel. Foundling wheels were abandoned in the late 19th century, but a modern form, the baby hatch, was reintroduced from 1952 and since 2000 has been adopted in many countries, most notably in Pakistan where there are more than 300. They can also be found in Germany (100), the United States (150), Czech Republic (88) and Poland (67).
