A woman who pleaded guilty to reckless driving for running over her nine-year-old son while dropping him off at school in Michigan has been ordered to serve 30 days in jail.

Tiffany Kosakowski, 36, told Kent County Circuit Court in Grand Rapids that she must 'live with this for the rest of my life.'

Judge Curt Benson sentenced her Thursday to 6 months in jail, with all but 30 days suspended. He called her actions 'simply inexcusable.'

Kosakowski's son hung from the passenger-side front door for nearly 50 yards in December at Chandler Woods Charter Academy's parking lot in Belmont before he lost his grip and was run over.

Authorities say he didn't want to stay at school.

The boy survived but suffered traumatic injury to his brain and also suffered broken bones and a fractured skull, WZZM reports.

He'll need extensive physical therapy and will require constant care.

John Rodriguez, the father of the woman's two children, shared that he hadn't seen his son in five years before seeing him in a coma at Helen DeVos Children's Hospital.

The mother had 30 letters of support but the judge questioned if she would still have that support if they knew what happened

'His head covered in wires [and] tubes, and sensors in his mouth and all over his little body,' Rodriguez added.

Rodriguez said he struggled not being able to see his children.

'For years, I have struggled to describe the behavior. So unstable, so irrational and so reckless,' he said.

Kosakowski is said to have told investigators that she knew her son was following her and walking besides the car, according to court documents.

'Ms. Kosakowski admitted to moving the steering wheel from left to right, then accelerating the vehicle knowing [her son] continued to be next to the vehicle,' the document stated.

The mother had 30 letters of support but the judge questioned if she would still have that support if they knew what happened.

'Of the 30 people who wrote the letters, I'll be quite blunt with you - I am not sure all of them would be as supportive, if they, like I, watched the security footage of this incident which is simply inexcusable,' Benson said.
