Baby Age calendar is a simple app that keeps track of your Baby's age. You can pin the age as a live tile on the screen. The age can be displayed either in Weeks or Years/Months format. You can also enter the expected date of the baby and it will track the arrival date of your little one. You can customize the live tile with a picture of your baby and select the background color of live tile as well. You can also add weight entries for your baby for each week and the app will plot a weight progress graph for you as well.
