The purpose of this study is to examine the effects of the Breastfeeding Self-Efficacy Resources Development Nurse Consultancy Program (EMÖZGEDAP), based on Dennis's Breastfeeding Self-Efficacy Theory along with the hypno-breastfeeding philosophy given to mothers and family relatives, on social support perception, breastfeeding self-efficacy and outcomes. The study will involve pregnant women and close others assigned randomly to the intervention (n=50) or control (n=50) groups in a state hospital in Turkey. Individual counseling will be provided to the intervention group within the scope of the EMÖZGEDAP, based on Denis's Breastfeeding Self-Efficacy theory and hypnobreastfeeding philosophy. EMÖZGEDAP, which will be applied to pregnant women and their family relatives, will consist of 5 sessions lasting 7.5 hours (2 sessions with the woman and her family relatives, two sessions with the woman alone, and one with her family relatives alone). The Antenatal Breastfeeding Self-Efficacy Scale will be evaluated before the counseling program is given in the antepartum period. Breastfeeding and Nutrition Results, Postpartum Breastfeeding Self-Efficacy Scale, Breastfeeding Self-Efficacy Scale for Fathers, Assessment Scale for Perceived Support of Close Others in Relation to Breastfeeding Self-Efficacy and Scale of Perception of Close Others' Support For Breastfeeding Self-Efficacy will be evaluated at the 1st, 3rd, and 6th months postpartum.

The World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) recommend that babies start breastfeeding within the first hour after birth and be exclusively breastfed for the first six months. In this situation, the baby is not given any other food or liquid, including water, defined as "full breastfeeding." Breastfeeding schemes were developed by Labbok and Krosovec in 1990 to ensure consistency in research. According to this scheme, breastfeeding methods are divided into full, partial, and symbolic, according to the baby's nutritional characteristics. According to the Turkey Demographic and Health Survey (TNSA, 2018) data, 98% of children are breastfed at some point, and 42% receive food other than breast milk in the pre-lacteal (before breastfeeding) period. In Turkey, 71% of children under two are breastfed within the first hour after birth, and only 41% of babies under six months are exclusively breastfed.

Self-efficacy is an essential factor in breastfeeding at the desired level. Influenced by Bandura's definition of self-efficacy, Cindy-Lee Dennis developed the "Breastfeeding Self-Efficacy Theory" by identifying the sources and influencing factors of Breastfeeding Self-Efficacy Perception. According to Dennis and Faux, a mother's breastfeeding self-efficacy includes whether she breastfeeds her baby, how much time she spends caring for her baby, her thoughts about breastfeeding, and her ability to cope with emotional difficulties during breastfeeding. Mothers with high self-efficacy encourage themselves to face challenges and try to solve events by thinking positively. These mothers prefer breastfeeding more, are more courageous, and act ultimately when they experience difficulties. Mother's breastfeeding self-efficacy is affected by four primary sources of information: The mother's previous experiences regarding breastfeeding, the examples the mother sees from others regarding breastfeeding, the support of the environment regarding breastfeeding, and the mother's psychological state regarding breastfeeding. Healthcare personnel should influence these factors to improve self-efficacy. Maternal breastfeeding self-efficacy has been identified as an important modifiable factor for successful breastfeeding.

Various factors, such as breastfeeding self-efficacy and social support, affect the sustainability of breastfeeding. The studies stated that social and especially spousal support is adequate for successful breastfeeding and the mother's decision to breastfeed early at birth. According to some studies, those with more social support have higher breastfeeding self-efficacy rates. The studies emphasized that family support is an essential factor in encouraging breastfeeding. The failure of family members to provide adequate breastfeeding support and information to women resulted in the use of formula. It is stated that the older generation, especially the baby's grandmother or paternal grandmother, plays a central role in various aspects of pregnancy decision-making and child-rearing within the family structure. A study conducted among mothers-in-law in Nepal found that mothers-in-law "view themselves as key providers and decision makers of perinatal care practices." Therefore, the woman needs to receive support from her social circle through participation and encouragement during breastfeeding.

Hypnobreastfeeding is a relaxation technique that helps improve the breastfeeding process by holistically caring for the mind, body, and spirit of breastfeeding mothers. Hypnobreastfeeding produces positive feedback by making the mother more relaxed, calm, and comfortable during breastfeeding, that is, an increase in the release of oxytocin and prolactin by the pituitary. In the hypnobreastfeeding philosophy, affirmation, relaxation, imagination, and visualization positively affect the subconscious. When the positive affirmations provided by hypnobreastfeeding are placed in the subconscious, they automatically affect daily life and actions and increase mothers' self-confidence. Therefore, hypnobreastfeeding is suitable for creating positive intention and motivation in breastfeeding, reducing anxiety and stress, maximizing the amount and quality of breast milk, increasing mother-baby bonding, and accelerating the involution process.
