Irena Ivic was driving the bus in Milwaukee County on the morning of December 22 when she spotted the child running on the side of the road just before 8am.
An on-duty bus driver in Milwaukee knew what she had to do when she saw a young boy when a baby wandering around alone near busy streets.
The toddler, who was less than one year old, was wearing only a onesie and a nappy.
A passenger on the bus took off her winter coat and draped it around the baby girl, who was cold to the touch. Police said the boy's mother, who may have been suffering from mental health issues, left the boy outside, and that the baby was placed with his father after the rescue, according to WITI.
This was the ninth lost or missing child found by MCTS drivers in recent years.
Ivic brought the freezing infant onto her bus and called for help.
After a period of time, emergency officials are seen arriving before they take the child, fast asleep in the driver's arms, with them.
On Thursday afternoon, Milwaukee County Executive Chris Abele and MCTS officials honored Ivic.
NOTE: Police first said the baby was a boy but later clarified that the child is actually a girl.
Ivic has been in Milwaukee for 12 years - and an employee of MCTS for five years. I'm shaking, ' she says.
"I have two lovely children and I am a human being and I find the child upset, and if I had the same situation again, I will, of course, again get help".
"She did a lot more than her job".
