Pregnant women who meet the inclusion criteria assigned to the Oketani Massage group will be informed about the study and their written and verbal consent will be obtained. Pregnant women will be asked to fill out the 'Introductory Characteristics Information Form' and 'Prenatal Breastfeeding Self-Efficacy Scale Short Form' at the first meeting before the training and then they will be given breastfeeding training and massage prepared with the Oketani method. 2 weeks after the training, the researcher will apply Oketani breast massage twice before the mother enters the operating room and once before the mother's first breastfeeding in the operating room or in the ward. One day after birth, they will be asked to answer the Postpartum Breastfeeding Self-Efficacy Scale Short Form, LACTH and Visual Comparison Scale Satisfaction (VAS-S) scale.

Pregnant women who meet the inclusion criteria and who are assigned to the control group will be informed about the study and their written and verbal consent will be obtained. Pregnant women will be asked to fill out the 'Introductory Characteristics Information Form' and 'Prenatal Breastfeeding Self-Efficacy Scale Short Form' at the first meeting. One day after birth, they will be asked to answer the Postpartum Breastfeeding Self-Efficacy Scale Short Form and LACTH.

The Oketani Method is based upon practical breastfeeding theory, but is original in its practice. Oketani breast massage improves breastmilk secretion, can prevent and treat problems such as mastitis. In addition, the massage is painless, allowing your body to relax and breathe, something very much appreciated by mothers.

The Oketani breast massage consists of massaging and milking the base of the breasts. These delicate glands are massaged as well as protected.

The first form of the scale developed by Dennis and Faux was designed as 33 items, but after a second study, Dennis revised the scale and created a 14-item short form. The Turkish validity and reliability study of the scale was conducted by Aluş Tokat et al. in 2017. The scale can be administered in prenatal and postnatal periods and measures how competent women feel about breastfeeding. The items of the five-point Likert-type scale are scored as not at all sure

(1), not very sure (2), sometimes sure (3), sure (4), very sure (5). The lowest score that can be obtained from all the evaluation scores of the scale is 14 and the highest score is 70. A low total score on the scale indicates a low perception of breastfeeding self-efficacy. In the original scale, the Cronbach's alpha reliability coefficient of the prenatal form was 0.87 and the Cronbach's alpha reliability coefficient of the postnatal form was 0.86.

The VAS is also used to measure other components besides pain, such as satisfaction.In our study, the VAS will also be used to assess mothers' breastfeeding satisfaction levels. The Visual Assessment Scale - Satisfaction (VAS-S) is a 10 cm ruler with the expression "Not satisfied" on one end and "Very satisfied" on the other end. The mother is asked to rate her satisfaction with breastfeeding after the training from 1 to 10. High scores on the scale indicate that the satisfaction of the recipients is also high
