Breastfeeding failures frequently result in issues. Lack of information about proper breastfeeding technique is one of the issues that frequently arises in nursing women, leading to uncomfortable nipples when the infant does not suck the nipple down to the areola. According to the 2022 Indonesian Demographic Health Survey, 79.3 individuals had painful nipples. The purpose of this study is to ascertain how well breastfeeding practices work in relation to the prevalence of painful nipples among nursing moms at the South Bulango Community Health Center in 2025. This kind of study employs a cross-sectional, quantitative research approach. 47 nursing women who were chosen by accidental sampling served as the study's population and sample. There is a correlation between breastfeeding practices and the incidence of sore nipples at the South Bulango Health Center in 2025, according to the results of statistical testing using the chi-square test. The p value (0.000) is not greater than α (0.05), so H0 is rejected and Ha is accepted. It is intended that the community, especially postpartum moms, would gain more understanding of the connection between breastfeeding methods and the prevalence of painful nipples in nursing moms.

Exclusive breastfeeding during the first six months of life is an effective public health intervention that contributes significantly to improving the health of both infants and mothers. Despite its well-documented benefits, the practice of exclusive breastfeeding still encounters various challenges, one of which is related to mothers’ attitudes toward breastfeeding. Health education is considered a key strategy in shaping positive maternal attitudes, which are essential for behavioral change. This study aims to analyze the effect of education on the importance of exclusive breastfeeding on mothers’ attitudes. The study employed a quasi-experimental design with a pretest–posttest one-group approach. The sample consisted of 30 mothers with infants aged 0–6 months, selected using a consecutive sampling technique. Attitudes were measured before and after the educational intervention using a Likert scale-based questionnaire. Data analysis included univariate and bivariate methods, with Fisher’s Exact Test at a significance level of 0.05. The results showed an increase in positive attitudes from 23.3% before education to 80.0% after. However, the statistical test indicated no significant relationship (p = 0.170). Nevertheless, education demonstrated potential in promoting positive attitude changes and remains important for continuous implementation.

Successful breastfeeding is a crucial factor in ensuring maternal and infant health, yet many postpartum mothers experience obstacles in optimally breastfeeding. One factor that plays a significant role in successful breastfeeding is family support and involvement. Families, particularly husbands and immediate family members, play a strategic role in providing the emotional, informational, and instrumental support mothers need during the postpartum period. This study aims to analyze the relationship between family roles and successful breastfeeding in postpartum mothers at TPMB Bdn. Neneng Banjarmasin. This study employed an observational analytical design with a cross-sectional approach. The sample consisted of 35 postpartum mothers with infants aged 0–6 months selected using purposive sampling. Data were collected using a structured questionnaire to measure family roles and successful breastfeeding, including aspects of early breastfeeding initiation, breastfeeding frequency, maternal comfort, and sustainability of breastfeeding practices. Data were analyzed univariately and bivariately using the Chi-square test with a significance level of p < 0.05. The results showed that most respondents received good family support and that the majority of postpartum mothers experienced successful breastfeeding. Bivariate analysis showed a significant relationship between family roles and breastfeeding success. In conclusion, family roles are significantly associated with breastfeeding success in postpartum mothers. This finding underscores the importance of a family-centered midwifery care approach in supporting breastfeeding success in community midwifery practice.

Nutritional problems can occur due to two factors, namely direct factors and indirect factors. Direct factors are unbalanced nutritional intake and infectious diseases. The achievement of Exclusive Breastfeeding in Pesawaran Regency during 2014-2019 fluctuated. In 2014, babies who received exclusive breastfeeding were 30.19%, in 2015 it decreased to 20.85%, in 2016 it increased to 49.76% and in 2019 it was 50.48% and still below the expected national target of 80% 11. Based on the results of a pre-survey of 30 breastfeeding mothers, there were 17 mothers (56.6%) with an average age of 15-25 years and most of them with low levels of education who did not provide exclusive breastfeeding on the grounds that the mother worked and did not get support from her husband to provide exclusive breastfeeding (Pesawaran Regency Health Office). The purpose of this community service activity is to increase mothers' knowledge about fulfilling balanced nutrition and exclusive breastfeeding so that toddlers are free from stunting.

Pneumonia is one of the leading causes of mortality in children under five, especially those living in households with active smokers. This study aims to determine the risk of pneumonia in toddlers from smoking families in the working area of Meuraxa Public Health Center, Banda Aceh City. The research used a case-control design with 33 respondents, consisting of 11 cases (toddlers with pneumonia) and 22 controls (toddlers without pneumonia). Data collection was conducted through a structured questionnaire and analyzed using the chi-square test. The findings revealed that the prevalence of pneumonia among toddlers from smoking households was 33.3%. There were significant associations between pneumonia incidence and several factors, including nutritional status (p = 0.024), immunization status (p = 0.034), exclusive breastfeeding (p = 0.027), parental smoking behavior inside the house (p = 0.009), and household ventilation (p = 0.017). Toddlers who were not exclusively breastfed, had poor nutritional status, incomplete immunization, poor air ventilation, and exposure to cigarette smoke at home were at higher risk of developing pneumonia. This study emphasizes the vital role of the family in creating a healthy, smoke-free home environment that supports children's well-being. Community-based interventions and educational programs are essential to prevent pneumonia and improve the quality of life of children, particularly in urban public health areas like Meuraxa.

Oxytocin massage is a technique used to stimulate the release of the hormone oxytocin, which plays a vital role in breastfeeding. Spinal massage stimulates the parasympathetic nervous system, which then triggers the release of oxytocin. This hormone causes contractions in the muscle cells surrounding the milk ducts, thereby promoting breast milk production. The purpose of this study was to determine the effect of oxytocin massage on increasing breast milk production in postpartum mothers. This study used a quantitative design with a quasi-experimental approach, namely a one-group pretest-posttest design. The study population was postpartum mothers with breast milk flow problems at the Bandarharjo Community Health Center, Semarang City. The sampling technique used was purposive sampling, where researchers selected samples based on certain characteristics. Data collection was carried out using a questionnaire. Data analysis used the Chi-Square test. The results of the study showed that the calculated Chi-Square value on the first day (62,000) was greater than the Chi-Square table (12,591), on the second day (54,866 > 23,684), and the third day (58,117 > 32,670). Based on these results, H0 was rejected and Ha was accepted, which means there was a significant effect of oxytocin massage on the smooth production of breast milk in postpartum mothers at the Bandarharjo Community Health Center.

This study aimed to examine the relationship between maternal anxiety levels and the timing of Early Initiation of Breastfeeding (EIBF) among primiparous mothers. EIBF, also known as Inisiasi Menyusu Dini (IMD), is a vital procedure that supports the establishment of effective breastfeeding and is recommended globally. Nevertheless, various maternal factors, particularly psychological conditions, may influence the implementation of EIBF. The main objective of this research was to determine whether increased anxiety during the peripartum period is associated with delays in initiating breastfeeding. A correlational analytic design with a cross-sectional approach was utilized in this investigation. The study population consisted of 77 eligible participants, while the final sample included 69 primiparous mothers who met the inclusion and exclusion criteria. Participants were chosen through purposive sampling. The independent variable was the maternal anxiety level, and the dependent variable was the timing of EIBF implementation. Data were gathered using a structured self-administered questionnaire designed to measure both variables. Statistical analysis was conducted using the Mann-Whitney U test. The findings demonstrated a p-value of 0.0389, which was below the significance threshold of 0.05 (p < 0.05), indicating the rejection of the null hypothesis. Therefore, the results revealed a significant relationship between anxiety levels and the timing of EIBF among primiparous mothers. Elevated anxiety was identified as a factor contributing to delayed initiation of breastfeeding. These findings highlight the importance of regular psychological screening and effective anxiety management for first-time mothers during childbirth to facilitate optimal postnatal care, particularly the timely initiation of EIBF.

Exclusive breastfeeding ensures the optimal development of children's potential intelligence. Babies without complete exclusive breastfeeding are more vulnerable to malnutrition. They face risks of both under-nutrition and over-nutrition. This study aims to determine the correlation between exclusive breastfeeding and nutritional status among infants in Kuta Cot Glie Public Health Center, Aceh Besar. This research was an analytical study with a cross-sectional approach. The sample consisted of 74 infants aged 0-6 months, selected using a Total Sampling technique. The study was conducted from May 1st to 23rd, 2025. The data were analyzed using univariate and bivariate methods with the Chi-Square test. Of the total 74 respondents, 44 respondents (59.5%) had a normal nutritional status. Additionally, 43 respondents (58.1%) were exclusively breastfed. The Chi-Square test showed a p-value = 0.001 < 0.05. The findings indicate a correlation between exclusive breastfeeding and nutritional status in infants. This study suggests that mothers exclusively breastfeed their babies. Therefore, mothers should also increase their knowledge by seeking information from various sources, such as clinics and professionals. This can help them understand the benefits of exclusive breastfeeding and how to prevent malnutrition in infants.

Breastfeeding success often faces various challenges, one of which is the infant’s anatomical condition, such as a lip tie. Successful breastfeeding can be achieved if mothers and infants develop good breastfeeding skills, including correct LATCH technique. This study aims to determine the effect of breastfeeding education on breastfeeding effectiveness using the LATCH method among postpartum mothers with infants with lip tie at Krakatau Medika Hospital Cilegon. The research design was a quasi-experiment with a one-group pretest–posttest approach. The study population included all breastfeeding mothers with infants diagnosed with lip tie, with a total sample of 29 participants selected through accidental sampling. The results showed that the rate of effective breastfeeding with good attachment before the education was 13.8% and increased to 41.4% after the education, with the mean breastfeeding effectiveness score rising from 4.86 to 6.97. The paired t-test revealed a significant difference between LATCH scores before and after the education (p < 0.001). It is recommended that Krakatau Medika Hospital develop a standard operating procedure (SOP) for breastfeeding education using the LATCH method.

Exclusive breastfeeding, sometimes known as ASI, is the practice of giving infants only breast milk, along with vitamins, supplements, and prescription medications for illnesses, and no other liquids or solid foods, either directly from the breast or expressed. The purpose of this study was to determine the relationship between maternal awareness of pumping and the effectiveness of exclusive breastfeeding at the Lampulo Community Health Center. This study used a cross-sectional methodology and an analytical quantitative design. 53 breastfeeding mothers constituted the study population. There were 53 respondents in total, and the sampling strategy used the total sampling method. A 20-question survey taken from Desriati Sinaga's 2024 study served as the instrument. The Lampulo Community Health Center in Banda Aceh conducted this study from May 19 to June 25, 2025. The Chi-square test results showed a p-value of 0.001 < 0.05. Based on the research findings, maternal awareness of expressing breast milk is related to the success of exclusive breastfeeding at the Lampulo Community Health Center. These findings are expected to form the basis for more comprehensive instructions for breastfeeding mothers to improve the success of exclusive breastfeeding with expressed breast milk.

Exclusive breastfeeding (ASI) is the provision of only breast milk to infants for the first six months without additional food or drink, including water. Breast milk has important benefits in improving infant health, growth, and survival. However, the coverage of exclusive breastfeeding in Indonesia, including in the Pasar Health Center in Prabumulih City, has not yet reached the national target of 80%. One factor influencing the success of exclusive breastfeeding is husband's support. The purpose of this study was to determine the correlation between husband's support and exclusive breastfeeding. The study used a quantitative approach with a cross-sectional design. The sample size was 49 mothers with infants aged 7–12 months. The study was conducted in the Pasar Health Center in May 2025. The results showed that 28 infants (57.1%) received exclusive breastfeeding, and 30 mothers (61.2%) reported receiving support from their husbands. Statistical tests using the chi-square test showed a significant relationship between husband's support and exclusive breastfeeding (p = 0.000). These findings indicate that husband's support plays an important role in successful breastfeeding. This research suggests that involving husbands in breastfeeding education and support is highly recommended to increase the coverage of exclusive breastfeeding in the community.

Maternal knowledge of newborn care plays an important role in maintaining neonatal health and preventing early complications. Parity is considered one of the factors that affect the mother's level of knowledge, as previous childbirth experiences can improve the understanding and skills of caring for the baby. However, primipara mothers often face challenges due to limited experience. This study aims to analyze the relationship between parity and newborn care knowledge in primipara mothers at the Tumpunglaung Health Center. The research method uses an analytical quantitative design with a cross-cutting approach. The study population was mothers who had just given birth at the Tumpunglaung Health Center, with a sample of 30 primipara mothers selected through purposive sampling. Data were collected using a structured questionnaire that included maternal characteristics and newborn care knowledge, including breastfeeding, hygiene, thermoregulation, and red flags. Data analysis was carried out by Chi-square test using SPSS at a significance level of p < 0.05. The results showed that most primitive mothers had moderate to low levels of knowledge, with a significant relationship between parity and newborn care knowledge. The conclusion of the study confirms the importance of strengthening education and counseling for primitive mothers to improve infant care practices and support neonatal health.

Exclusive breastfeeding for the first six months of life is an important nutritional intervention that plays a role in supporting infant growth and preventing growth disorders. Although the coverage of exclusive breastfeeding in Indonesia has increased, differences in infant growth outcomes based on nutritional sources remain an issue that needs to be examined contextually. This study aims to analyze the effect of exclusive breastfeeding on infant growth at the Labuha Community Health Center, South Halmahera Regency. The study uses a quantitative approach with an observational analytical design and a comparative cross-sectional design. The study sample consisted of 30 infants aged 3–9 months selected using total sampling technique. The independent variable was the infant's nutritional source (exclusive breastfeeding and breastfeeding supplemented with formula milk), while the dependent variables included weight gain and length gain. The data were analyzed univariately and bivariately. The normality test was performed using the Shapiro–Wilk test, and the difference analysis was performed using the independent t-test. The results showed that there was no significant difference in infant weight gain based on nutritional source (p = 0.334). However, there was a significant difference in infant length gain, with infants who were exclusively breastfed showing better linear growth than infants who received a combination of breast milk and formula (p = 0.006). The conclusion of this study shows that exclusive breastfeeding has a significant effect on infant length growth, but not on weight gain. These findings emphasize the importance of exclusive breastfeeding in supporting linear growth as a key indicator of healthy infant growth.
