Under normal conditions, the umbilical cord is removed 5-15 days after birth. It dries up and falls within days. It is extremely important to determine the factors that cause the prolongation of the falling time of the cord, which poses a serious risk for infection. The aim of this study is to determine the effect of umbilical cord care training given to primiparous mothers on the duration of cord fall. It is a randomized controlled type of research. The population of the research will be primiparous mothers who gave birth in the obstetrics clinic of a university hospital. A pilot study will be conducted to determine the number of samples. As a result of the pilot study, power analysis will be performed and the number of samples will be determined. Inclusion criteria of mothers in the study; Data collection tools: "Descriptive Questionnaire" and "Questionnaire for Umbilical Cord Care" will be used to collect research data. Randomization will be done as odd days of the week and even days of the week for sample selection in the study. Primiparous mothers giving birth on odd days of the week will form the group that will receive umbilical cord training, while primiparous mothers giving birth on even days of the week will form the group that does not receive training. The research will be carried out in two stages. In the first stage of the research, after informing the mothers about the study, they will be invited to the research. Written consent will be obtained from mothers who volunteered to participate in the study. Then, the "Descriptive Questionnaire" prepared to describe mothers and babies will be filled. In the second stage of the research: the mothers will be called 15-20 days after the first interview and the "Question Form Regarding Umbilical Cord Care" will be filled.

Data Collection:

Stage 1: A pilot study will be conducted with 10 mothers in order to evaluate the appropriateness of the forms and scales used before the research.

Stage 2: The purpose of the research and how to record the data will be explained to the mothers. The mothers in the sample group will be informed about the path followed in practice and the research, and their verbal and written consent will be obtained.

Stage 3:The mothers who meet the sample selection criteria will be randomly and equally distributed into 2 groups through a program in the computer environment, and randomization will be provided.(http://www1.assumption.edu/users/avadum/applets/RandAssign/ GroupGen.html) (1st experimental education group, 2nd control group).

Stage 4: Then, the "Descriptive Questionnaire" prepared to describe mothers and babies will be filled. In the second stage of the research: the mothers will be called 15-20 days after the first interview and the "Question Form Regarding Umbilical Cord Care" will be filled. Umbilical care training will be given to primiparous mothers who give birth on odd days of the week and meet the research criteria, and the training brochure will be printed out and given to mothers. The training will be given face-to-face during the postpartum period when the mother is stabilized. In order to increase the effectiveness of the training, the content of the training will be reinforced by making mutual questions and answers.

The control group will be given routine clinic care. Stage 5: The time of fall of the umbilical cord will be recorded in the data collection form.

Stage 6:The analysis and reporting of the obtained data will be done.
