A cross-sectional study was conducted to investigate the knowledge, attitudes, and practices of 60 caregivers regarding complementary feeding and its impact on the nutritional status of their children aged 6–23 months in Panicuason, Naga City, Philippines. Face-to-face interviews were conducted to collect data using pre-designed and pre-tested questionnaires. Descriptive statistics and Pearson’s R Correlation tests were used to analyze the data at p<0.05. The results indicated that the households involved had poor conditions in terms of educational attainment, occupation, and household income of the caregivers. The prevalence rates revealed a medium level of underweight (10.0%) and stunting (23.4%), and a poor level of wasting (5.0%). The KAP results demonstrated medium knowledge, positive attitudes, and poor practices among the caregivers. Several KAP components were found to be significantly associated with socioeconomic factors and water sanitation practices. The study found a weak positive correlation between weight-for-age and employment and a weak negative correlation between height-for-age and caregiver-child relationship. This study highlights the urgent need for nutrition education interventions focused on complementary feeding to improve the knowledge and practices of the caregivers. Such interventions are essential for enhancing child nutrition outcomes and potentially influencing positive changes in the attitudes of the caregivers.
