An Indiana mom was arrested Tuesday for allegedly leaving her toddler in a hot car during a Department of Child Services interview with her newborn, according to a report.

Jennifer K. Ost, 27, arrived with her newborn to an appointment with a DCS at Community Pediatrics in Anderson – about 45 miles northeast of Indianapolis, Fox 59 reported. According to court documents, she gave birth to her son four days earlier and signed him out of the hospital against medical advice.

Police said the appointment was scheduled at 2:30 p.m. but Ost arrived at 2:40 p.m. After a physician examined her baby, she became “belligerent” and started cursing at the DCS employee during the interview, court documents said.

The hospital received a phone call around 4:30 p.m. regarding a small child in the parking lot, Fox 59 reported. A police officer found a young boy in the car, watching a movie on cell phones. It was reportedly 86 degrees outside.
