The etiology of postpartum depression is often multidimensional and may be related to a poor childbirth history, multiple births, uncomplicated pregnancies, adolescent mothers, pregnant women who give birth prematurely, have pregnancy complications or are hospitalized with a newborn, or have disharmonious family relationships, and some mothers may develop postpartum depression because the sex of their newborn does not match their desired gender. The main manifestation of postpartum depression is a poor mood, most of which develops within two weeks after delivery. Many mothers show a particularly bad mood, do not want to talk to others, and may become disconnected from their husbands and families, and some may lack confidence in their lives. In this case, it is recommended that the mother seek help promptly and can go to a hospital psychology department or psychiatric department for consultation and diagnosis.
