Child care of working mothers has become a social issue. For such a reason, baby-sitter’s role has become more important than ever especially for working mothers who can’t get help of grandparents. NINEFIVE has started this project to help working mothers out there. The project is simply the baby care journal with real-time notification, called "MomNMom." The biggest feature of this app is that all baby activities that baby-sitter enters is updated on working mom’s mobile with notification. Considering the varieties of baby-sitters’ age, UI is designed as much as simple and intuitive. Also the app contains essential features as memo and calendar.
