Separation anxiety disorder (
SAD) is a
psychological condition in which an individual experiences excessive
anxiety regarding separation from home or from people to whom the individual has a strong
emotional attachment (e.g. a parent, caregiver, or siblings). It is most common in infants and small children, typically between the ages of 6–7 months to 3 years. Separation anxiety is a natural part of the developmental process. Unlike SAD (indicated by excessive
anxiety), normal separation anxiety indicates healthy advancements in a child’s cognitive maturation and should not be considered a developing behavioral problem.
