Postpartum depression can last months if it is left untreated, notes the Mayo Clinic. Postpartum depression is a more severe form of "theÂ baby blues." While the baby blues might last only a few weeks and don't require treatment, postpartum depression usually won't go away without treatment.
Postpartum depression, or PPD, can develop within the first 2 months of the baby's life, according to BabyCenter. In some cases, PPD makes a woman feel as though she can't care for her baby. Women experiencing PPD might suffer from feelings of extreme sadness, anxiety or anger. These women are usually irritable and may find it difficult to perform daily care tasks. Any woman who feels she is suffering from PPD should contact her doctor immediately for help.
