1. The researcher used purposive sampling to select 22 schools from two zones in Chennai to collect data on the feeding practices of mothers with children under 21 months of age. 2. A total of 22 schools were selected from which 22 mothers and 44 grandmothers were interviewed using a pre-tested questionnaire to gather information on feeding times and foods given to children under 21 months. 3. The data collection methods and sample selection process are described in detail, including development of the questionnaire, pilot testing, and selection of participants from specific schools to capture a representative sample.
