Introduction: The issue of malnutrition and stunting in toddlers often stems from parenting mistakes, particularly the inaccuracies in the Practice Feeding. Although the facilities of the Toddler Mother Class are available at the Community Health Center, their utilisation tends to be suboptimal due to an approach dominated by one-way theoretical lectures. This community service activity aims to optimise the Toddler Class into an educational platform based on interactive practices to enhance mothers' knowledge of infant and child feeding practices. Methods: This activity was carried out at the Kesambi Primary Health Center in Cirebon City, involving 15 mothers with toddlers aged 0–24 months and 2 cadres as sustainability partners. The program implementation method is divided into three comprehensive stages: the preparation stage (policy coordination and assessment of the needs of mothers with toddlers), the implementation stage (IYCF education ), and the evaluation stage (measurement of cognitive aspects through pre-test and post-test). Results: The educational intervention led to a substantial improvement in maternal knowledge regarding IYCF practices. Prior to the intervention, baseline evaluation showed that only 33.3% of mothers demonstrated good knowledge. Following the implementation of the participatory educational sessions, the proportion of mothers in the good knowledge category increased markedly to 86.7%, reflecting a successful shift in maternal knowledge. Conclusion It is concluded that the education provided to mothers of toddlers, particularly with a different educational model in terms of methods and media usage, where participatory-applicative education is very effective in stimulating cognitive changes in mothers of toddlers in the practice of feeding infants and toddlers. It is recommended that the Puskesmas integrate the interactive practice-based discussion education model into the health promotion program scheme to ensure the sustainability of specific nutrition interventions at the primary service level.
