Ivic-Drobnjak's Facebook profile says she's from Prokuplje, a city in southern Serbia. "When I saw him I pull over my bus and immediately went to pick him up".
As the bus sat waiting for police and EMS responders to arrive, one passenger walked up to Ivic as she held the baby in the driver's seat.
This is the dramatic moment a bus driver rescues a baby girl that she spotted wandering alone on a street with no shoes or pants on.
An alert Milwaukee bus driver came to the rescue of a toddler found wandering barefoot on a freeway overpass in frigid temperatures.
The boy, who was less than a year old, was wearing just a nappy and onesie when driver Irena Ivic spotted him on 22 December, along her route in Milwaukee, MCTS said. "I have my children too", Ivic said.
Police said the girl had been left outside by her mother, who is thought to be suffering from a mental health crisis. Officers were later able to reunite the boy with his father.More news: #SaveRahaf: Activists' lightning campaign made Saudi teen's flight a global cause

Milwaukee police told WITI no charges were filed in the case.
Ivic, who will be honored Thursday by Milwaukee County Executive Chris Abele, spotted a boy alone on a freeway overpass near 4th and Mitchell.
"She did a lot more than her job".
"Oh my god, oh my god", she said. "I don't take that kind of compassion for granted".
This was the ninth lost or missing child found by MCTS drivers in recent years. "And if I find myself in the same situation again, I will, of course, help again".
