World Mental Health Day is on 10 October, and this year the World Federation for Mental Health has chosen the theme "Lived experiences heard: real voices, real change", putting a focus on how people's experiences should inform the way mental health services are designed and delivered. This feels particularly relevant to maternal health. Pregnancy, birth and postpartum bring significant change to a woman's physical health, relationships, routines and sense of identity. Mental health is a major part of that picture, although it is not always treated that way.
