The first children were admitted on 25 March 1741. Within the Foundling Hospital, mothers were required to hand over their child in person. Between 1756 and 1760, the hospital was required to admit every baby brought to its doors in return for government funding. The numbers of children taken in during this time resulted in soaring mortality rates which gave the hospital a reputation that too many died in their care. It took the hospital several years to recover its reputation. Restrictions were imposed to not overwhelm the hospital, which initially included babies to be under two months old and free from disease.
Rather than abandonment, the mothers took their babies to the Foundling Hospital, but many were hopeful that their circumstances would change so that they could one day reclaim their child. Every child admitted to the Foundling Hospital was baptised and given a new identity. Mothers also left a token that could be used to identify their child if they returned to reclaim them. The Foundling Hospital kept meticulous records of every child who passed through the institution.
Once received, the children were sent to be wet-nursed with foster families in the countryside and they stayed there until they were about five years old. Then they were returned to live and be educated in the Foundling Hospital until around the age of fifteen.
Girls were then generally apprenticed for domestic service and boys were apprenticed into a variety of occupations, usually for seven years. Many boys were also trained for military service.
During the mid-1700s several Foundling Hospital branches were set up, albeit temporarily, to cope with the large number of children received at the time. These were:
Ackworth Foundling Hospital (1757-1773) - More than 2,600 children came through its doors.
Shrewsbury Foundling Hospital (1758-1772) - was the second largest branch hospital, caring for almost 1,200 children in total.
Aylesbury Foundling Hospital (1759-1768) - housed 40-100 children at a time
Westerham Foundling Hospital (1760-1769) - Chartwell, the home of British prime minister Winston Churchill, was once the Westerham branch hospital in Kent. The branch cared for 469 children in total.
Barnet Foundling Hospital (1762-1768) - cared for 40 children at a time
Chester Foundling Hospital (1763-1769) - cared for 306 children in total, many of whom lived with nurses in the countryside around Chester.
The Foundling Hospital relocated to Redhill, Surrey in 1926, and a new school was built at Berkhamsted, Hertfordshire which opened in 1935.
