A PMH-C (Perinatal Mental Health Certified) is a professional credential from Postpartum Support International (PSI) for specialists—including therapists, nurses, and doctors—who possess advanced training, experience, and competence in treating perinatal mood and anxiety disorders (PMADs).  See a the PSI PMAD Fact Sheet.
 

Perinatal Mood and Anxiety Disorders (PMADs)

• affect at least 1 in 5 birthing people during pregnancy and/or during the first year after childbirth

• are the #1 complication of pregnancy and childbirth

• are a spectrum of emotional complications that can affect expectant or new parents at any point during pregnancy or the first year after birth.

• Onset of symptoms may be gradual or sudden, but should never be ignored. 

• are often caused by a “perfect storm” of changes in biology, physiology, lack of sleep, transition in identity (from pregnancy to parenthood) and one’s own expectations of parenthood versus the reality of a new baby​

• most commonly impact the birthing person, but can also impact fathers, partners, adoptive parents 
   

The good news is that PMADs are temporary and are treated with some combination of self-care, social support, talk therapy, and, if necessary, medication.
