Postpartum mood disorders are not uncommon after having a baby, affecting one in eight woman. They generally fall into three groups: the blues, postpartum depression, and postpartum psychosis (which is rare). Know the symptoms and talk to your health care provider if you notice any of the following: crying more than usual, feelings of anger, feeling overwhelmed, sleep problems, wanting to isolate yourself from loved ones, feeling disconnected  from your baby, worry that you will hurt your baby, feeling guilty, or doubting your ability to be a good mother.
