This research is a randomized controlled experimental study. The research will be conducted in SANKO University Sani Konukoğlu Application and Research Hospital NST unit and Gynecology Service in Gaziantep. The population of the study will consist of pregnant women admitted to SANKO University Sani Konukoğlu Practice and Research Hospital Obstetrics Outpatient Clinic. When power analysis was performed, the minimum sample size per group was found to be 16. It is planned to take a minimum of 40 people per group. Data Collection Tools "Personal Information Form", 'Prenatal Breastfeeding Self-Efficacy Scale', 'Primiparous Breastfeeding Motivation Scale' and 'Breastfeeding Self-Efficacy Scale Short Form' were used to collect the data.

Personal Information Form This form prepared by the researcher consists of a total of 20 questions that can determine the socio-demographic and obstetric characteristics of pregnant women.

Prenatal Breastfeeding Self-Efficacy Scale It was developed by Wells et al. in 2006 to determine pregnant women\&amp;#39;s perceptions of breastfeeding self-efficacy. It was adapted into Turkish by Aydın and Pasinlioğlu in 2016. The scale consists of a total of 20 items and has no sub-dimensions. The scale is 5-point Likert type. The items of the scale are; "Not at all sure" (1 point), "Somewhat sure" (2 points), "Quite sure" (3 points), "Very sure" (4 points), "Completely sure" (5 points). There are no reverse scored items in the scale. The lowest score that can be obtained from the scale is 20 and the highest score is 100. The scale has no cut-off point. An increase in the score obtained from the scale indicates an increase in the perception of breastfeeding self-efficacy. The Cronbach\&amp;#39;s alpha coefficient of the Turkish version of the scale is 0.86. The Cronbach\&amp;#39;s Alpha coefficient in this study was 0.95 Primiparous Breastfeeding Motivation Scale It was developed by Stockdale et al. in 2013 to determine the factors affecting breastfeeding motivation in primiparous women. The scale was adapted into Turkish by Akçay and Demirgöz Bal in 2019. The scale consists of a total of 29 items and is 7-point Likert-type. The scale has 4 sub-dimensions.

Breastfeeding Self-Efficacy Scale Short Form It is a 33-item scale prepared by Dennis and Faux (127) in 1999 to assess breastfeeding self-efficacy levels. A short form of the 14-item Breastfeeding Self-Efficacy Scale was developed by Aluş-Tokat et al. in 2010. The scale is a 5-point Likert scale. The lowest score that can be obtained from the scale is 14 and the highest score is 70. The scale has no cut-off point. The higher the score obtained from the scale, the higher the breastfeeding self-efficacy. The Cronbach Alpha value of the scale is 0.94.

Implementation of the Study: The data will be collected face-to-face by the researcher herself. Patients who meet the inclusion criteria will be included in the control and intervention groups using face-to-face interview method. The implementation of the study will take place in 7 stages for 2 intervention groups (Hypno-breastfeeding and progressive muscle relaxation exercise).

Pregnant women in the experimental and control groups will receive routine breastfeeding education during pregnancy follow-up. After cesarean delivery, pregnant women will receive routine postpartum nursing care and the interventions, medication/order list, time and method of administration will be applied in a standardized manner. Pregnant women in the control group will not receive any intervention. The interventions applied to the experimental groups are given below. Before the interventions were implemented, the prepared materials were sent to the experts via e-mail and expert opinion was obtained. For hypno-breastfeeding; training chart, relaxation text and audio recording, for progressive muscle relaxation exercise, training chart, relaxation text and video were prepared. Necessary corrections were made in the relaxation texts and schedules in line with expert opinions. Hypno-breastfeeding and progressive muscle relaxation exercise practices will be performed by the researcher herself.

Evaluation of the Data IBM SPSS Statistics 22 package program will be used for data analysis. In statistical evaluation; categorical measurements will be summarized as number and percentage, continuous measurements will be summarized as mean, deviation and minimum-maximum. Chi-square test and Fischer\&amp;#39;s Exactness Test will be used for comparisons of categorical variables. The conformity of the variables to the normal distribution will be examined using visual (histograms and probability graphs) and analytical methods (Kolmogorov-Smirnov/Shapiro-Wilk Tests). One-way Anova test will be used for more than two variables in groups that conform to normal distribution, while Kruskall Wallis tests will be used for more than two variables in groups that do not conform to normal distribution. Bonferroni analysis will be used in Post Hoc analyzes to determine the source of the difference between groups. The results will be evaluated at 95% confidence interval and p\&amp;lt;0.05 error level.
