Su Clinica Familiar in Willacy County, Texas established a nurse-midwifery service in 1972 that has expanded to the point of doing the majority of the deliveries in that county. High quality of care of infants and mothers has resulted from a prenatal program which places great emphasis on nutritional counseling and supplementation coupled with careful observance of a pregnant woman's condition, delivery in a clinic facility without the traditional restraints on the mother and family, and a 24-hour post-partum clinic stay followed by two home visits to ensure the health maintenance of mother and infant.
