Welcome to the official site of the Marce Society's Mother and Baby Unit (MBU) Special Interest Group. We are a global community of professionals and advocates dedicated to improving perinatal mental health care through specialized services that support mothers and their infants together.
About Us
Vision
A world where every mother experiencing severe perinatal mental illness has access to intensive, specialist care — in whatever form best meets her and her baby's needs.
Mission
The MARCÉ MBU SIG connects clinicians, researchers, and multidisciplinary professionals worldwide who care for women with the most severe forms of perinatal mental illness. Through regular knowledge exchange, multidisciplinary collaboration, and internationally coordinated research, we advance understanding of intensive perinatal care — across mother and baby units and other specialist modalities — to improve outcomes for women and their families globally.
