Pregnant women who meet the inclusion criteria assigned to the Pecha Kucha 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', the 'Antenatal Breastfeeding Self-Efficacy Scale Short Form' and the 'Infant Feeding Attitude Scale (IOWA)' before the training at the first encounter, and then breastfeeding training prepared by the Pecha Kucha method will be given. 2 weeks after the training, she will be followed up by phone and asked to answer the Pospartum Breastfeeding Self-Efficacy Scale Short Form, Infant Feeding Attitude Scale (IOWA) and Visual Comparison Scale Satisfaction (VAS-M) scale. 4 weeks after the training, she will be asked to answer the Pospartum Breastfeeding Self-Efficacy Scale Short Form, Infant Feeding Attitude Scale (IOWA) and Visual Comparison Scale Satisfaction (VAS-M) 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 'Descriptive Characteristics Information Form', 'Antenatal Breastfeeding Self-Efficacy Scale Short Form' and 'Infant Feeding Attitude Scale (IOWA)' at the first encounter. After 2 weeks, she will be followed up by telephone and asked to answer the Pospartum Breastfeeding Self-Efficacy Scale Short Form, Infant Feeding Attitude Scale (IOWA) and Visual Comparison Scale Satisfaction (VAS-M). After 4 weeks, she will be asked to answer the Pospartum Breastfeeding Self-Efficacy Scale Short Form, Infant Feeding Attitude Scale (IOWA) and Visual Comparison Scale Satisfaction (VAS-M).

The Pecha Kucha method will be prepared in the form of a presentation consisting of 20 slides each shown for 20 seconds. The Pecha Kucha presentation lasts 6 minutes and 40 seconds, and most slides present only images. This method is planned to be used in breastfeeding education as it will be more memorable because it contains more visual, auditory and short information.

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, not very sure, sometimes sure, sure, very sure. 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.

Women's attitudes towards breastfeeding and to predict breastfeeding duration as well as the choice of infant feeding method. The scale consists of 17 items on a 5-point Likert scale ranging from (strongly disagree) to (strongly agree). While 9 items in the scale are positive about breastfeeding, 8 items contain positive statements about formula feeding. Formula feeding items are reverse scored. The total attitude score ranged from 17 points (reflecting a positive attitude towards bottle feeding) to 85 points (reflecting a positive attitude towards breastfeeding). Cronbach Alpha internal consistency coefficient was 0.71 and the scale was found to be reliable.
