Purpose: This is a randomized controlled trial designed to investigate the effects of Kangaroo Mother Care (KMC) applied in the early postpartum period to primiparous mothers on breastfeeding success and the perception of the maternal role.

Methodology and Sample:

Setting and Period: The study will be conducted at the Bucak State Hospital Delivery Unit between June 2025 and June 2026.

Sample Size: Based on G*Power analysis (alpha=0.05, power=80%, effect size d=0.566), a total of 112 mothers (56 intervention, 56 control) will be included, accounting for a 10% potential attrition rate. Participants will be assigned to groups using the sealed envelope method and randomization via www.random.org.

Intervention:

Experimental Group: Following routine care, the newborn will be placed in a "chest-to-chest" position on the mother's bare chest for Kangaroo Care. Intermittent KMC will be maintained for 24 hours, during which breastfeeding attempts will be supported.

Control Group: Mothers and newborns will receive only the hospital's routine care (standard skin-to-skin contact and breastfeeding support).

Data Collection Tools:

Personal Information Form, Semantic Differential Scale-Myself as a Mother (to measure maternal role perception), LATCH Breastfeeding Assessment Tool (to evaluate breastfeeding success).

Intervention Protocol:

Experimental Group: In addition to routine delivery care, newborns will receive Kangaroo Mother Care (KMC). The newborn, wearing only a diaper and a hat, will be placed in an upright "chest-to-chest" position on the mother's bare chest. The infant's head will be maintained in a neutral physiological position, and the back will be covered with a blanket. This intermittent KMC application will be initiated following the first breastfeeding attempt and maintained throughout the first 24 hours postpartum, including during transport and periods of maternal rest.

Control Group: Participants will receive the standard hospital protocol (routine skin-to-skin contact immediately after birth and standard neonatal care). No additional KMC intervention will be applied by the study team.

Data Collection and Measurement Points:Data collection will be conducted at two specific time points to evaluate the effectiveness of the intervention:Baseline (0 Hour): Immediately following the first breastfeeding attempt (within the first hour postpartum), the LATCH Breastfeeding Assessment Tool will be administered to both groups to establish baseline breastfeeding success.Post-Intervention (24th Hour): At the end of the 24th hour postpartum, the LATCH tool will be re-administered to evaluate the change in breastfeeding success. Additionally, the Semantic Differential Scale-Myself as a Mother will be administered at this time point to compare maternal role perception between the two groups.

Statistical Analysis: The normality of the data will be assessed using the Skewness and Kurtosis coefficients. For Breastfeeding Success: A Two-Way Mixed ANOVA will be used to analyze the interaction between "Group" (Experimental vs. Control) and "Time" (0 vs. 24 hours).For Maternal Role Perception: Since this variable is measured only at the 24th hour, an Independent Samples t-test (or Mann-Whitney U test, depending on normality) will be used for inter-group comparison.All analyses will be performed using SPSS 25.0 with a significance level of p < 0.05.
