Infant and young child feeding practices directly affect the nutritional status of children under two years of age and, ultimately, impacting child survival. Improving infant and young child feeding practices in children 0–23 months of age is therefore critical to improved nutrition, health and development of children. (UNICEF, 2007). The present study entitled “Infant Feeding and WASH Practices of the Mother Visiting Hospital in Aizawl, Mizoram” was conducted on 300 mothers of infant and young child (0-24 months) visiting hospitals. The study respondents were selected randomly from both Government and private hospital of Aizawl, Mizoram. The study assessed the knowledge and practices of mothers regarding breastfeeding and complementary feeding of infant and young children who visited hospitals of Aizawl, Mizoram using a structured questionnaire.72.3 percent infants received breast feeding within 1 hour of birth and 79 percent were exclusively breast fed. Demand feeding was being practiced by 83.3 percent mothers. The mean age for initiating weaning foods was 5.8 months. 84.3 % did not give any prelacteal feeds. Although, WASH practices were followed by more than 90 percent of the respondent however only 40 percent washed their hands before serving food.
