Before undertaking the data collection, 2 research assistants were recruited and trained on using the “opportunistic observation form” and each item of the form was reviewed to ensure proper understanding. The observation form was translated in Kinyarwanda and reviewed again to ensure its conformity with the English version. The form was piloted with mothers of young children located in the neighboring villages of the study community. The observers (the principal investigator and the research assistant) arrived at participants’ homes in the morning and remained at the house until the lunch meal is prepared and the child had eaten to fill out the observation form. The date of the visit was not announced to the mothers and the choice of food was free.
