Background: Febrile seizures are benign neurological disorders in children under the age of five and often make parents distressed and frightened leading to a relevant reduction in the quality of care. Aim: This study aimed to examine the effect of bite-sized teaching sessions on parents' knowledge, attitude, and practice regarding febrile seizures in children under five. Setting: The study was carried out over a period of six months from May to October 2021 in the Pediatric department at Governmental hospital, El Menoufia Governorate, Egypt. The study adopts a quasi-experimental research design to perform this study on 80 parents of children with febrile seizures from the age of 6 months to 5 years old and selected by convenience sampling technique. Two tools were used for gathering data. First tool: A structured interviewing questionnaire sheet. The second tool: An observational checklist to evaluate the parents' practice for first-aid management of febrile convulsion. Results: Findings of the current study indicate statistically significant differences between pre and post-tests regarding parents' knowledge and care practices for children with febrile convulsion at 5% and 1% levels of statistical significance. Conclusion: There was a marked improvement in parents' knowledge, attitude, and practice post-implementation of the bitesized teaching program. Recommendation: Continuous bite-sized teaching sessions should be scheduled regularly for parents in the Pediatric Units to reinforce the quality of care and improve children's outcomes.
