Background: Surgery is a stressful experience for children and their parents, affecting the way their social, psychological, environmental, and physical systems operate. Raising Mother's knowledge of post-operative care can help to avoid or lessen issues and encourage a speedy recovery. Aim of the study was: To evaluate the effect of discharge instructions for mothers on the post-operative recovery of their children with abdominal surgery. Research design: A quasi-experimental research design was used in the current study. Sample: A purposive sample of 70 mothers had children undergoing abdominal surgery and was divided equally into study and control groups. Setting: Minia University, Hospital for Pediatric Surgery's, pediatric surgery department was the site of the present investigation. Tools: Three tools were used: a structured interview questionnaire (I), a questionnaire to test mothers' knowledge (II), and a sheet to assess post-operative problems (III). Results: After the discharge program was put into place, there was a statistically significant change in the levels of knowledge held by mothers in the study group compared to the control group (P =0.001). At one week and one month after program implementation, the study group had substantially fewer postoperative complications than the control group (P =0.043). Conclusion: Results showed that, in comparison to the control group, mothers whose children were part of the research group knew enough to be discharged safely. Complications after surgery were less common in the children's study group compared to the control group. Recommendations: Periodic education sessions and guidelines for mothers whose children are undergoing abdominal surgery. Sessions aimed at increasing nurses' knowledge of the advantages of discharge planning for children. Using telenursing to provide follow-up care
