Background: Exclusive breastfeeding means babies are given only breast milk and nothing else: no other milk, food, drink, not even water for one day (24 hrs) before the survey was conducted. It prevents 13% of childhood mortality; i.e, at least 1.2 million children worldwide would be saved every year. The objective of this study was to assess the prevalence exclusive breastfeeding (EBF) practice and its associated factor among mothers who have infants less than six months of age in Motta town, East Gojjam, Amhara Regional State, Ethiopia. Method: A community based quantitative cross-sectional study was conducted from April 7, 2015 to May 7, 2015. A simple random sampling technique was applied after taking all registered mothers who have infants less than six months old from local health extension workers of each kebele. A total of 423 mothers with infant less than six months old were included in this study. The data was collected using an interviewer administered questioaire. Both bivariate and multivariate logistic regression analyses were used to identify factors associated with exclusive breastfeeding practice. Result: Prevalence of exclusive breastfeeding was 50.1%. Mothers with young infants aged 0-1 month (Adjusted Odds Ratio [AOR] 3.86: (1.64, 9.07), unemployed mothers (AOR 3.01: 1.46, 6.20), low income mothers (AOR 3.61: 1.75, 7.45), mothers who received breastfeeding counseling in pregnancy (AOR 2.76: 1.52, 4.99), fed colostrum (AOR 3.50: 1.45, 8.45), didn't give prelacteal feeds (AOR 4.48: 1.82, 11.03) and were supported by their husband (AOR 2.67: 1.04, 6.95) were more likely to practice exclusive breastfeeding than their counterparts. Conclusions: Prevalence of exclusive breastfeeding practice in study area was lower than country recommended level. Age of the child, maternal occupation, income, breastfeeding counseling during antenatal care, husband support of breastfeeding and colostrum feeding were independent predictors of exclusive breastfeeding practice. Recommendations to increase exclusive breastfeeding practice are revising postpartum maternity leave, increasing health professional's habit of breastfeeding counseling through training, involving husbands during counseling, educating mothers and the community as a whole to avoid traditional practices that hinder exclusive breastfeeding up to six months.
