The Birthday Bank is a donation method churches began using in the early 1900s to provide help for children in the care of OBHC. In the early years, the gift was usually a penny for each birthday celebrated. As time went by, the penny became a dollar and so on.
The Department of Child Care was established in 1956 and entrusted by the Convention with the operation of Christian services to children and their families. In 1985, the Department of Child Care and the Department of Retirement Centers and chaplaincy were combined to create the Special Care Ministries Office. In 1988, the name was changed to Family Care Ministries Office and included the Child Care, Adult Care, and Special Care Ministries. A separation of Adult Care and Child Care in 1993 created two new entities. In that year, Oklahoma Baptist Homes for Children was established as an affiliate corporation of the Baptist General Convention of Oklahoma with its own President and Board of Trustees. OBHC is now the largest provider of private, non-profit residential child care in the state.
