Population proportion to size was used to ensure equal representation. Data was collected using pre tested semi structured questionnaire & analysed using open epi like descriptive statistics with univariate & multi variate logistic regression were used. Results: Total of 165(55%) subjects were females, with majority 206(68.7%) Muslim by religion and 161(53.7%) lived in the nuclear family. The prevalence of morbidities among infants was 209(69.7%).
