It is common to see in the workplace that some mothers experience transient, mild dysphoria in the postpartum period, the cause of which is related to the sharp drop in estrogen in the body after delivery, and not to personality traits or a history of poor pregnancy and childbirth. However, trivial matters in life such as future visits by family members, husbands’ silence, neonatal jaundice, and insufficient milk production are common triggers. The symptoms include depression, tearfulness, crying, mild mood disorders, easy fatigue and agitation, which may last for several days, but the prognosis is good, and very few cases may develop into postpartum depression. Therefore, sufficient care and assistance should be given to the mother during the early puerperal period, and sympathetic listening, rather than critical counseling, is necessary to alleviate the depressed mood.
