A distressed baby has been rescued from a hot car in Gepps Cross on Wednesday morning as temperatures soared over 30C.
A traffic officer discovered the infant and attempted to break into the car.
The child’s parent was eventually found and the baby was released from the vehicle and taken to the local Children’s Hospital as a precaution.
At the time the temperature was 31C.
Police warned that children should not be left in cars which can result in death.
“Just cracking the window is not enough, and don’t think it’ll be okay ‘just for a minute’,” a police spokesman said
Public are encouraged to call the police or triple-o if they are concerned for the welfare of a child or animal.
The incident follows a primary-aged girl and baby boy found trapped in a car around 1pm on December 30.
The siblings' 29-year-old mother, a Keysborough woman, will be charged on summons with two counts of leaving a child unattended.
The outside temperature at the time was 25C, but police say could easily have been up to 60C inside the vehicle. Both children were suffering from heat stress and were taken to hospital as a precaution.
Horror summer for hot car incidents
The news comes after what has been a horror summer for children left in hot cars, with a Queensland man charged on December 1 after his daughter was found sweaty and without food or water in a car outside a pub in Allenstown, near Rockhampton.
Just one week prior to that in Canberra, an infant and a five-year-old were rescued from a hot car in the city's south after passersby noticed the children locked inside on a 41C day.
Police and child safety advocates have repeatedly warned that leaving your children unattended for any length of time in a vehicle is unacceptable and could lead to death in a very short period of time.
According to Kidsafe Executive officer Christine Erksne, 5,000 children had to be rescued from children from hot cars nationwide last year.
"Police and ambulance officials are reporting it's still a regular occurrence and it's still a big problem," she said.
"The temperature can quickly rise inside the car, and the temperature can be 30 degrees different inside the car compared to outside and it's very dangerous for those little bodies.
"No access to water or cooling can have a major impact on the body.
"If you do have a child in the back seat, put your wallet or bag in the back so when you get out of the car you don't forget what's in the back," she advised.
"If there's going to be a change of routine, it's good to have some sort of trigger."
