A Wisconsin babysitter has avoided jail time after she took a plea deal for leaving three toddlers in a hot car while she got her nails done.

Hannah Sprang, 24, was sentenced to probation by Manitowoc County Circuit Judge Bob Dewane on Monday after she pleaded no contest to three counts of child neglect, court records show.

Sprang was accused of leaving three children, including one child who was a year old and a pair of two-year-olds, inside her unattended vehicle for nearly 90 minutes while she visited a nail salon, according to a criminal complaint obtained by WLUK.

Police were called to the unidentified spa for a report of children alone in a vehicle on July 18 last year. 

'The babysitter seemed unphased by the reason for contact or that she left three children in an unattended and not running vehicle,' the complaint said.

'[Sprang] stated that she was at [the spa] to get her nails done and that they had made her wait because they were not ready for her.'

She allegedly told police that her appointment was for 11am, but the staff did not take her right away, and that she checked on the children multiple times throughout her appointment. 

However, the responding officer wrote in the report that surveillance footage disproved Sprang's claim. 

'I was provided access to the video surveillance and learned that [Sprang] arrived in the chair at 1049 hours,' the officer wrote.

'At 1149 hours (one hour later), [Sprang] left to check on the children. [Sprang] then returns and does not leave until 1217 hours when she observed my squad behind her vehicle in the parking lot.

'The total amount of time the children were in the unattended vehicle was one hour and twenty-eight minutes.'

When Sprang was confronted about the 'misinformation' she provided about checking on the children, the officer noted that the caregiver still 'appeared to be unphased.'

According to the criminal complaint, the outside temperature that day was 69 degrees Fahrenheit, but the vehicle's interior temperature was 81.1 degrees. 

'When I reached into the vehicle, the vehicle's interior was not overly warm. The interior was warm but not extremely warm,' the filing stated.

'The children did not appear to be in any physical distress, although crying, probably due to the amount of contact.' 

When the officer asked Sprang for the parents' contact information, the cop said she was 'not real cooperative.'

'[Sprang] intermittently provided information to me; however, felt the need to be texting and calling each parent prior to me having a chance to talk to them,' the complaint said.

'[Sprang] stated that she had made notification to each parent and they were responding to our location.'

At the sentencing hearing on Monday, Assistant District Attorney Angelina Scarpelli read a statement from the parents of one of the two-year-old victims. 

'Even today, there are still moments when we pull into a parking spot, and he says, "Don't leave me in here,"' the statement said.

'Every time, we reassure him that we would never leave him alone in the car. Hearing your child say those words is heartbreaking.'

Sprang apologized for her actions, telling the court, 'I would just like to say I apologize and I regret deeply what I did, and I just apologize for what I did. And I know it was wrong.'

The judge sentenced her to two years of probation and ordered her to be permanently banned from offering babysitting or daycare services.
