Across low-and-middle income countries, the case for perinatal mental health is increasingly well made. What comes next is harder: how do you actually build integrated perinatal mental healthcare inside maternal and child health services that are already stretched? From Policy to Practice is a five-part online workshop series for the people responsible for making integration happen: ministry officials, maternal and newborn programme managers, mental health programme managers and district health managers, NGOs supporting MCH and reproductive health services, development partners and researchers across the region.
