This project aims to build an effective tracking and monitoring for the modern age parents who don’t have enough time to take care everything about their babies by providing some special functions that offer trustworthy information from clearly source and professional medical staff verification. Moreover, parents and pediatrician can simply communicate in an online form which is application called Oh! My Baby. It is an easy-to-use application that could be beneficial if parents have a tool which can remind them to give their baby vaccines and medicines, track the growth of baby, connect to baby’s doctor directly and help parent to take care of baby in every day that’s why we have decided to create Oh! My Baby application for mobile phone.
