The Neonatal Behavioral Assessment Scale (NBAS),also known as the Brazelton Neonatal Assessment Scale (BNAS), was developed in 1973 by Dr. T. Berry Brazelton and his colleagues. This test purports to provide an index of a newborn's abilities, and is usually given to an infant somewhere between the age of 3 days to 4 weeks old. This approach was innovative for recognizing that a baby is a highly developed organism, even when just newly born. The profile describes the baby's strengths, adaptive responses and possible vulnerabilities. This knowledge may help parents develop appropriate strategies for caring in intimate relationships to enhance their earliest relationship with the child.
