Which observation in a new mother may indicate a need for further assessment for postpartum depression?

The observation of a new mother showing a lack of interest in eating may indicate a need for further assessment for postpartum depression. This behavior can be a significant red flag as it suggests possible emotional distress or a loss of interest in activities that were once enjoyable, including self-care. It is important to monitor maternal mental health closely in the postpartum period, as a lack of appetite can be both a symptom of depression and a potential contributor to further health issues due to inadequate nutrition.

In contrast, the other observations indicate positive behaviors and emotional states. Engaging enthusiastically in baby care, being proactive in seeking support, and expressing joy about being a new mother are all signs of healthy adjustment to motherhood and suggest good mental well-being. These behaviors typically demonstrate that the mother is coping well and has a support system in place, which are protective factors against postpartum depression. In this context, a lack of interest in eating stands out as a concerning symptom that warrants further evaluation.
