Abstract

We tested the prospective associations between coparenting relationship quality and breastfeeding duration among 164 dual-earner, cisgender, heterosexual couples identifying as mothers and fathers at the transition to parenthood. We hypothesized that mothers who perceived higher quality (more supportive and less undermining) coparenting relationships would breastfeed for a longer duration. At 3 months after childbirth, mothers reported their perceptions of coparenting relationship quality using the Coparenting Relationship Scale. Mothers reported their breastfeeding behaviors at four time points—when their infant was 3, 6, 9 months and 12–36 months old. Survival analysis revealed that higher quality coparenting relationships were associated with longer breastfeeding duration. This association was only observed among families of girls. This study highlights the interactive role of coparenting relationship quality and infant sex as proximal contexts that may shape breastfeeding practices.
