APP CLOSING DIRECTLY ON MAINPAGE ON CLICKING BACK BUTTON, WHEN NOT ON HOME SCREEN

BUG DEFINITION
There is an issue in main page, where we cannot go back to home page but it just closes the app.
for example - right now I am on my home page, now when I will go to list of babies page now on clicking back it will just close the app rather than going back to home page.
So, a confirmation dialog should be shown while quitting the app.
It is a good approach as now days most of the phones are coming with gesture for back, so basically if someone by mistakenly made back gesture it will close the app, so we can give them a pop up alert that do they really want to close the app. And if they are not a at home screen then we can redirect them to home screen as told in above example.
