This Milwaukee bus driver's story is going viral online for her heroic gesture as she went above the call of duty when she stopped the bus to save a toddler.

Irena Ivic, the bus driver, was driving on a freeway overpass when she spotted a barefoot toddler running on the road, Milwaukee County Transit System spokesman Matt Sliker said. The child was only wearing a red onesie and a diaper and was quickly walking to an intersection.
