Abstract Purpose Maternal perinatal social support is theorised to promote offspring social-emotional development, yet few studies have prospectively examined this relationship. Findings may inform preventative intervention efforts, to support a healthy start to emotional life. Methods This study examined whether maternal social support perinatally predicts infant social-emotional development at 12 months of age in two longitudinal cohort studies: The Australian Temperament Project (ATP) (n = 1, 052 mother-infant dyads 653 mothers, M ageₐtbirth = 32. 03, 88% Australian-born; 1, 052 infants, 52% girls) and The Triple B Pregnancy Cohort Study (Triple B) (n = 1, 537 dyads 1, 498 mothers, M ageₐtbirth = 32. 53, 56% Australian-born; 1, 537 infants, 49% girls). Social support was assessed at pregnancy (third trimester) and eight-weeks post-birth. Infant social-emotional competencies (ATP: Brief Infant and Toddler Social and Emotional Assessment (BITSEA), Competencies Scale; Triple B: Bayley Scales of Infant and Toddler Development-Social Emotional Scale) and problems (ATP: BITSEA, Problems Scale; Triple B: Ages and Stages Questionnaires: Social-Emotional Scale), were assessed at 12-months of age. Results In ATP, social support was associated with lower offspring problems (pregnancy: β = -0. 15; post-birth: β = -0. 12) and greater competencies (pregnancy: β = 0. 12; post-birth: β = 0. 16) at 12 months. In Triple B, social support also predicted lower offspring problems (pregnancy: β = -0. 11; post-birth: β = -0. 07) and greater competencies (pregnancy: β = 0. 07) at 12 months. Findings did not indicate an association between support at eight-weeks post-birth and subsequent competencies (β = 0. 06). Conclusions Evidence suggests that perinatal social support promotes healthy infant social and emotional development. These results underscore the critical importance of social support for mothers transitioning into parenthood.
