Police were responding to reports of a 4-month-old baby who had stopped breathing when the woman's black Mercedes Benz hit the driver's side door of the police car parked on Oradell Avenue, Police Chief Kenneth Ehrenberg said.
The officer wasn't inside the vehicle at the time and no injuries were reported, Ehrenberg said.
The baby was in stable condition and an investigation was under way, the chief said.
