Many parents in Switzerland experience perinatal depression, and its impact on families and society is serious. Yet important gaps remain in both research and healthcare. Pregnant and new parents are not routinely checked for depression, and many do not receive the support they need. Care is also still largely based on a cisgender, heterosexual model, which means we lack knowledge about the needs of different kinds of families. There is an urgent need to better understand the needs and experiences of all parents and the professionals who care for them, to develop guidelines that take sex and gender into account, and to improve services in collaboration with those directly affected.
