Reciprocal Mother-Infant Voice Exposure in the Neonatal Intensive Care Unit

This randomized controlled trial evaluates the effect of reciprocal maternal‐infant voiceexposure on maternal attachment and breastfeeding outcomes in a neonatal intensive careunit (NICU). Infants in the intervention group are exposed to recordings of theirmothers' voices, while mothers simultaneously listen to recordings of their infants'sounds between the 6th and 12th postpartum hours. The intervention is administered every2 hours for 30 minutes. Outcomes include maternal attachment, breastfeedingeffectiveness, breastfeeding self‐efficacy, infant feeding intention, perceivedinsufficient milk, and expressed breast milk volume. Neonatal physiological parametersand blood gas values are also assessed. The findings aim to support family‐centered NICUcare through non‐invasive auditory interventions.
