Abstract
Humanitarian pediatrics represents a transformative evolution of pediatrics that responds to global polycrises that disproportionately harm children. Grounded in child rights and humanitarian principles, it integrates clinical care, public and humanitarian health, research, policy, and advocacy to address both direct and indirect threats to children's survival, development, and wellbeing. Central to this approach is Témoignage, or bearing witness, through which pediatricians use ethical authority and evidence to expose injustice and advance accountability.
