The researcher will perform oxytocin massage to the fifth-sixth rib along the patient's spine.

The researcher will apply pressure in different ways to the reflex points on the patient's sole with her fingers.

Patients in the control group will not undergo any intervention and will receive their routine care.

Primiparous women will be visited 12 hours after cesarean delivery, women will be informed, verbal and written consent will be obtained from women who want to participate in the study, and pre-test data will be collected by the researcher. The pre-test data of the research were it will be collected by face-to-face interview technique in approximately 25 minutes. The height of the fundus part of the uterus will be measured with a tape measure. The woman's physiological parameters will be measured by the researcher. At this stage, the patient will receive an oxytocin massage for 10 minutes while in a sitting position. One hour after the application (13th hour after cesarean section), the physiological parameters of the patients will be measured again by the researcher. 24 hours after the application (36 hours after cesarean section), the data of the patients will be collected again by the researcher and uterine involution and physiological parameters will be evaluated.

The Insufficient Milk Perception Scale consists of a total of 6 questions and a single subscale. The first question on the scale is whether the mother finds her milk sufficient. The first question is answered as yes or no. The other 5 questions are scored between 0-10. The given score indicates that as it approaches zero, the mother perceives her milk as inadequate, and as she approaches 10, she perceives enough. A minimum of zero points and a maximum of 50 points can be obtained from the scale. The high score indicates that milk is sufficiently perceived.

The scale consists of 29 items and has a 7-point Likert type and 4 sub-dimensions. These sub-dimensions; the value given to breastfeeding (items 1,2,4,6,8,10,12,14,15,20,24,25,28), self-efficacy (items 9,16,17,18,19,26,29 ), midwife support (items 21,22,23,27), success expectation (items 3,5,7,11,13). As the score obtained from each sub-dimension increases, the breastfeeding motivation level of that sub-dimension increases.

The State-Trait Anxiety Inventory (STAI) is a commonly used measure of trait and state anxiety. It can be used in clinical settings to diagnose anxiety and to distinguish it from depressive syndromes. It also is often used in research as an indicator of caregiver distress. Form has 20 items for assessing for state anxiety. State anxiety items include: "I am tense; I am worried" and "I feel calm; I feel secure." All items are rated on a 4-point scale (e.g., from "Almost Never" to "Almost Always"). Higher scores indicate greater anxiety.

This form is a form prepared by the researcher in line with the literature, in which the measurement of the length of the uterus is recorded and the uterine involution process of postpartum women is evaluated. The length of the uterus; It will be done by measuring the distance between the fundus of the uterus and the symphysis pubis with the help of a tape measure. When measuring uterine length, women will be ensured that their bladder is empty and the same tape measure will be used in all measurements.
