Research on the dyadic effects of parental depression and burnout in non‐Western contexts remains limited.\n\n\nObjective\nThis study examined how parental depressive symptoms and burnout predict toddlers' externalizing behaviors in a Turkish dyadic context.\n\n\nMethods\nWe recruited 144 mother–father dyads with 1‐to‐3‐year‐old toddlers, and they responded to questionnaires assessing depressive symptoms, parental burnout, and toddler externalizing problems.\n\n\nResults\nNeither maternal nor paternal depressive symptoms predicted mother‐ or father‐reported externalizing behaviors. However, parental burnout and depressive symptoms were positively associated within and across partners. Notably, maternal parental burnout significantly predicted father‐reported and marginally predicted mother‐reported externalizing problems.\n\n\nConclusion\nThese findings suggest that maternal burnout may play a more prominent role than depressive symptoms in early externalizing problems.\n\n\nImplications\nGiven the interdependent nature of parental well‐being, maternal burnout emerges as a critical target for early prevention and intervention efforts.\n\n"]
