Quality of mother-infant interaction, breastfeeding, and perinatal mental health

Introduction: The quality of mother-infant interactions is crucial for child development. Studies show that breastfeeding contributes to maternal sensitivity and the development of a positive mother-infant bond. Maternal mental health difficulties negatively impact both maternal sensitivity and breastfeeding. Thus, it is unclear whether breastfeeding contributes to the quality of mother-infant interactions independent from mental health. The purpose of this study is to examine the contribution of exclusive breastfeeding at 3 months postpartum to the quality of the mother-infant relationship at 6 months postpartum, controlling for maternal mental health in acommunity sample of mothers in Chile. Materials and method: Eighty women completed self-report measures of mental health and breastfeeding during the third trimester of pregnancy and 3 and 6 months postpartum. At 6 months after childbirth, the mother-infant interaction was assessed by coding a free-play session between mothers and infants. Logistic regression analysis was used to examine the contribution of breastfeeding practices and mental health to the quality of mother-infant interactions. Results: Exclusive breastfeeding at 3 months postpartum increased the likelihood of displaying positive mother-infant interactions controlling for maternal mental health. Mothers who continued to breastfeed at 6 months postpartum reported less symptoms of antenatal depression and anxiety and higher levels of sensitivity and cooperation towards their infants. Conclusion: Breastfeeding contributes to maternal sensitivity and cooperation even when controlling for maternal mental health. Implications for health practitioners and limitations due to the sample characteristics are discussed.
