Strength and limitation of the study
The questionnaire used for this study is based on WHO IYCF indicator parameters. A standard pretested questionnaire was used. This paper is the first to be conducted in the study area and complementary feeding self-efficacy was not conducted elsewhere in Ethiopia. However, the limitation of this study might have had an information bias for the knowledge, attitude, and self-efficacy questions, which might have led to the over-reporting of the desirable answers due to a fear of being judged. Second, since it was a cross-sectional study, causal inferences between variables cannot be investigated.
