Which of the following symptoms is most characteristic of postpartum blues and typically resolves within two weeks without intervention?

A. Hallucinations and delusions are not characteristic of postpartum blues; they are signs of postpartum psychosis, which is a psychiatric emergency requiring immediate intervention. B. Crying easily and frequently, resolving within two weeks, is the hallmark symptom of postpartum blues. It typically begins within the first few days after delivery and resolves spontaneously without medical intervention. Other common symptoms include mood swings, irritability, and anxiety. C. A complete lack of interest in the newborn suggests postpartum depression, a more serious condition that requires intervention and does not resolve spontaneously within two weeks. D. Persistent sadness lasting more than two weeks is indicative of postpartum depression, not postpartum blues. Postpartum blues are self-limiting and short-lived, whereas postpartum depression requires active treatment and support.
