Randomization In order to ensure similarity between groups; Stratified block randomization was used to assign the women in the sample group to the experimental and control groups. According to the stratified block randomization method, the imbalances that may occur in the experimental and control groups are limited. In this method, block randomization is performed within each stratum after stratification according to risk factors (Akın & Koçoğlu, 2017; Kanık, Taşdelen & Erdoğan, 2011). Since the mode of delivery affects the content of breast milk, women will be divided into two layers as vaginal delivery and cesarean section in terms of delivery type (Table 1).

In order to determine the strata group of the woman who was found to meet the research criteria and accepted to participate in the study, a list of assignments was created through the website www.randomizer.org by making 6 blocks with a combination of 4 .

Experiment: A Control: B

n the study, all mothers who come to the Lactation/Relactation outpatient clinic will be informed about the study, and mothers who accept the study will have to fill out the "Conformity to Criteria Form" created by the researcher. Between the ages of 20-35, postpartum 1-5. Participants who gave birth after the 37th week of pregnancy, did not have literacy problems, mental disabilities and communication problems, did not have chronic diseases, did not use any medication, and volunteered to participate in the study will be included in the study. by milking, 2 ml of first milk will be taken from the participants in the control group (via the milking pump). The collected milk will be taken to the laboratory for analysis by the researcher.

Breast milk expressed by hand or by pumping. Milks will defrize, then, will warm and will homogenize using Miris Ultrasonic Processor for 5 seconds, and analyzed for protein content performing Miris®️ HMA. analyzes breast milk content. The results of protein contents will be recorded in the breast milk analysis form.
