The fourth annual Perinatal and Infant Mental Health Conference brings together leaders, clinicians, researchers, educators, trainees, policy makers, and advocates, individuals with lived experiences, and community partners working across perinatal and infant mental health to foster meaningful connection, shared learning, and collective action. At its core, the conference is designed to bring people into the same room, across disciplines and sectors, to start conversations, break down silos, and promote deeper integration and collaboration in how we support families during the perinatal and early childhood period. The conference is organized around five interconnected areas essential to advancing perinatal and infant mental health: clinical services, research, training and education, community engagement and lived experiences, and policy and advocacy. Through a keynote address, panels, and interactive discussions, the conference highlights innovative work and diverse perspectives across each of these domains, while emphasizing the importance of cohesive and intentional multidisciplinary efforts. Grounded in the understanding that family wellbeing during the perinatal period is shaped by biological, psychological, relational, social, and systemic factors, the conference centers a two-generational and relational lens. It acknowledges that supporting mothers, fathers, birthing and non-birthing parents, infants, siblings, and the broader family unit requires collaboration among professionals from many disciplines and systems of care. By honoring diverse voices, elevating lived experiences, and creating space for dialogue and partnership, the conference aims to promote both knowledge and connection. Ultimately, it seeks to strengthen a shared sense of purpose and togetherness in advancing perinatal and infant mental health, recognizing that meaningful progress depends on working collectively to meet the complex and evolving needs of families.
