Objectives of study
1. Assess the current knowledge level of working mothers regarding breastfeeding.
2. Determine the effectiveness of the education program on milk literacy.
3. To find the relationship between job knowledge test scores and choices among different people.

Hypothesis 
H1: There was a significant difference between the pretest and posttest in the knowledge of working mothers about breastfeeding.
H2: There was a significant correlation between the pretest knowledge of working mothers about breastfeeding guidelines and their choices in different populations.

Conceptual Framework 
The researcher adopted Kenny's open model as an architectural model. This sentiment was echoed by Janet. W. Kenny was born in Scotland in 1946. Data analysis. Analyzing relevant data allows the researcher to obtain support for this study, information on the existence of the problem, the impact of changes, data processing, and statistical analysis.

Methodology: The tool's development process was split into two parts:
Part 1: Demographic data - population Socio-demographic data is prepared to collect personal data from courses.
Part 2: Structured Information Questionnaire, the structured information questionnaire has 15 questions divided into three areas.
Part A: Questions on the importance of breast milk for mothers after birth.
Part B: Breastfeeding Knowledge Questions for Working Mothers.
Part C: Questions on the knowledge of working mothers about breastfeeding techniques.

Results: The post-test mean (13.23) exceeds the pre-test mean (4.97).The average difference in results between the pre-and post-tests is (8.26). The test score has decreased to 23.65, indicating a value at the p<0.00 001 level. As a result, the study hypothesis H1 is approved.
This shows that SIM effectively improves mothers' knowledge of breastfeeding guidelines. No information. The pre-mean is 4.97, standard the deviation is 8.26, the standard deviation is 1.09, the degrees of freedom is 29, the paired t-value is 23.65, and the p-value is <.00001. When the posttest is 13.23, the mean difference is 8.26, the standard deviation is 1.57, degrees of freedom is 29, the paired t-value is 23.65, and the p-value is <.00001. The mean of the post-test (13.23) is greater than the mean of the pre-test (4.97). The test score reduction is 23.65, which is significant at p<0.00001, and the mean difference between the pre-test and post-test scores is 8.26. Hence, the study hypothesis H1 is approved. This shows that SIM effectively improves mothers' knowledge about breastfeeding.

Conclusion and Recommendation: The findings indicate that more interventions are needed to increase breastfeeding awarenes. Learning the milk supply guide will increase the knowledge of working mothers.
