Abstract Under nutrition is one of the leading causes of morbidity and mortality of children in most developing countries including Ethiopia Maternal and child nutrition related issues are main concerns of mothers, family or care takers, health care providers, organizations and governments that work in the field of nutrition Since nutritional information has significant role in the reduction of maternal and child malnutrition, it is important to avail relevant nutritional data on various media including the web to enhance the effort that the health sector is putting to reduce maternal and child morbidity and mortality Therefore, this study is intended to design and develop web based maternal and child nutrition information system that give hands for the health sector effort towards the reduction of maternal and child morbidity and mortality Interview and document analysis were used as main tools to capture the system requirement, and the data was analyzed using inductive approach The project used selected artifacts of an object oriented system analysis and design technique to design the web based system The finding of the study shows that there is low level of awareness in the community about maternal and child nutrition The prime source of Information on nutrition during pregnancy and lactation were not health professionals at the maternal and child health department, instead, they get it from other pregnant women, family or friends Therefore, availing information is one way of intervention which strengthen the availability of information in a feasible and cost-effective manner vii | P a g e viii | P a g e 7.2 Recommendations The following recommendations are made based on the findings:  The system should add more functionality and content  The system should be upgraded to the full-fledged site  The content of the web should be periodically updated  The content of the web should be translated in multiple local language  In order to enhance easy access of information, the system should be deployed in all facilities that provide maternal and child health service  Mobile app should be developed for the system 55 | P a g e Reference Ethiopian
