Many women suffer from mild depression during the first week after delivery, it is commonly known as Postpartum blues or Baby blues. It is usually time limited but may progress to postpartum depression if the symptoms persist for over four weeks.
The mother is easily irritable, loses interest in all activities, may have negative feelings towards the infant or express concerns about her ability to care for her child. Some medical illnesses (e.g. hypothyroidism) may mimic postpartum depression and need to be carefully evaluated.
