Two weeks postpartum, a mother reports persistent sadness and lack of interest in activities. This pattern is more consistent with postpartum depression than the blues due to:

• A. The time of day symptoms occur
• B. The baby's feeding pattern
• C. The severity and persistence of symptoms like 'constant doubt' and 'hopelessness'
• D. The mother's sleep quality

Answer: (C)

The key idea is distinguishing postpartum blues from postpartum depression by how severe and how long the symptoms last. Blues are mild mood changes that start after birth and typically clear within about two weeks. When sadness is persistent two weeks after delivery and includes more intense, debilitating thoughts like constant doubt and hopelessness, it indicates postpartum depression rather than the blues. The persistent cognitive symptoms signal a depressive episode that impairs functioning, which is not characteristic of the transient blues. While sleep difficulties or mood fluctuations can occur in both, the distinguishing factor here is the severity and persistence of these depressive thoughts and feelings.
