Complementary feeding is defined as the practice of addition of solid, semi-solid or soft foods to infant’s diet once the infant reaches 6 months of age along with breastfeeding. According to NFHS-5, in Himachal Pradesh, 68.3% children aged 6-8 months are receiving solid or semi-solid food and breastmilk. Among children age 6-23 months only 19% are receiving an adequate diet. We have planned this study with the objective to assess the complementary feeding knowledge of Anganwadi workers (AWW) of Shimla city. Methods: We conducted a Cross-sectional study from 15th October 2021 to 15th October 2022 among 82 Anganwadi workers (AWW) of Urban Block, Shimla district of Himachal Pradesh. Anganwadi workers were interviewed on a structured, pretested and validated questionnaire. Collected data was entered into Microsoft excel spreadsheet and analyzed using Epi info version 7. Results: Mean knowledge score obtained in our study was 21.6±2.73, with 26 as maximum knowledge score and 14 as minimum score obtained. 46.3% of the Anganwadi workers had overall very good knowledge about complementary feeding practices but 52.4% of the workers does not know how to check the consistency of the complementary food given to infants and young children. 53.7% of the Anganwadi workers believe that non vegetarian food should not be given to children below 2 years of age. Conclusion: Reorientation trainings and workshops on complementary feeding practices from time to time would help in increasing the knowledge of Anganwadi workers about complementary feeding and will also improve their skills for proper implementation of complementary feeding practices in the community.
