Problem: While partner support benefits breastfeeding outcomes, its impact across perinatal stages on maternal co-parenting perception is unclear.
Background: Spousal involvement plays a vital role in successful breastfeeding and maternal well-being.
Aim: This study aimed to examine the effects of spousal participation in breastfeeding interventions at different perinatal stages on maternal co-parenting perceptions and infant feeding practices for full-term infants.
Methods: Pregnant women who received antenatal care and delivered at our hospital, together with their partners, were recruited and categorized by the timing of partner involvement in breastfeeding activities: both antenatal and postnatal (Group A); antenatal only (Group B); postnatal only (Group C); and no antenatal education but routine postnatal guidance (Group D). Maternal breastfeeding self-efficacy and coparenting perception were assessed at 6, 12, and 24 weeks postpartum.
