There is an app for that...

We dont have baby monitor but we have two lovely children. One evening sitting outside a holiday apartment close to the window, hoping that in case of baby noise we can easly hear it we started to look for the way of getting far away. Than I told to my wife: look, we have two mobile phones, maybe they can work as a baby monitor, lets open AppStore, "there must be an app for that". We found Baby monitor, and since then we can spend our holiday evenings being much more free in terms of taking care of our children :)
