Aim: In this prospective, randomized controlled study, it was aimed to examine the effects of early half-swaddle and kangaroo care practices in term babies on maternal sleep quality and postpartum depression.

Design: The prospective, randomized controlled study

The study will include n=136 mothers who gave birth at term at Trakya University Health Research and Application Center Birth Service. Between 10.09.2023 and 10.07.2024, n=136 (34=control, 34=semi-swaddled, 34=kangaroo care, 34=semi-swaddled and kangaroo care) women who volunteered to participate in the study will be conducted randomly in four groups: case and control.

Before starting the research, four groups will be randomly formed among the mothers. As a randomization method, mothers who meet the sampling inclusion criteria determined in the research will be identified and listed. Individuals to be taken into four groups will be determined by randomization method from the random numbers table. (http://www.stattrek.com/statistics/randomnumber-generator.aspx).

Research data: It was collected using the Survey Form, Edinburgh Postpartum Depression Scale (EPDS) and Pittsburgh Sleep Quality Index (PSQI).

Survey form; It which was prepared by the researchers by reviewing the literature consists of 5 main sections and a total of 82 questions, including the personal characteristics of the mother who gave birth preterm, the characteristics of the birth and the baby, the characteristics of sleep, the characteristics of the baby's sleep pattern, and the characteristics of the baby's growth and development.

Edinburgh Postnatal Depression Scale (EPDS): The scale was developed by Cox and Holden (1987). Adapted to Turkish by Engindeniz, Küey, and Kültür (1996). It is used to determine the risk for depression in the postnatal period and to measure the level and change of violence. It is a self-assessment scale. It is applied to postpartum women. It contains a total of 10 questions and measures depression. It provides a four-point Likert type measurement. The- Page 2 of 8 directive is at the beginning of the scale and subjects are asked to mark the substance most relevant to their situation when filling in the subjects. The total score of the scale is obtained by adding these item scores. As a result of the cut-off point scale study conducted in Turkey and it has ben calculated as 12/13.

Pittsburgh Sleep Quality Index (PSQI): PSQI is a self-reported screening and assessment questionnaire that details information on the type and severity of sleep quality and disorders within the last month. It was developed by Buysse et al., and its validity and reliability study in Turkish was performed by Agargün et al. PUKI evaluates sleep quality in the last month. 18 items and 7 components (subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, use of sleeping pills, daytime dysfunction) are included in the scoring. Each item is evaluated over 0-3 points and the sum of 7 component points gives the total PUKI score. The total score ranges from 0 to 21, with higher scores indicating worsening sleep quality. A total PUKI score of ≤5 is considered "good sleep", and >5 is considered "bad sleep".

The survey form and scales will be applied to all four groups at the first meeting. In the groups where half swaddle, kangaroo care and both half swaddle and kangaroo care are applied, necessary information about sleep, such as the mother's sleep duration, frequency of waking up, duration of wakefulness and reasons for waking up, will be recorded before the start of the study and for 24 hours. During the 6 months of the study period, mothers will be called every month by phone and their questions about the application methods and the application will be answered. All scales will be repeated at the beginning, 1st, 3rd and 6th months, and the mother's sleep monitoring for the last 24 hours will be requested again. Practical training on semi-swaddle and kangaroo care will be provided to mothers at the first meeting through prepared presentations.

Data collection The mean scores of PSQI and EPDS at the beginning,1st, 2nd, 3rd, and 6th months of the half swaddling and kangaroo care group Intervention.

Half swaddle: HS applied to a newborn baby makes the baby feel completely safe, as if in the womb. After laying the soft fabric or baby blanket, it was placed in the supine position. Half swaddling was done so as not to restrict the baby's arm and leg movements. HS was performed 15 minutes before each sleep during the day until the 3rd month.

Kangaroo care: The application was applied at twice a day and for 60 min, every day for 6 months in a row. While the mothers were taken to the NICU and practiced at home prior to kangaroo care, hand hygiene and breast care were provided within the scope of infection prevention rules. During KC, the mother placed her baby between two breasts, and the baby's breast was placed on the mother's breast in an upright position. During the application of KC, a quiet, calm and suitable environment was created so that comfort of the baby and mother would not be disturbed. The mother and baby are covered with a blanket. The ambient temperature was 26 centigrade degrees during the kangaroo care. In the continuation of the KB application, the mother was asked to breastfeed her baby. In order to prevent the risk of aspiration of the baby after breastfeeding, the baby was placed in the left lateral position so that the mother and the baby could lie down together. The application steps of the mother's KC were observed by the researcher and the deficiencies, if any, were corrected by discussing with the mother during / after the application.

Control group: The mothers in the control group were given routine care.
