There is science behind why this happens.

Science behind the syndrome
David Diamond, a professor of psychology at the University of South Florida, has worked closely with KidsAndCars.org. He focuses on cognitive neuroscience, including the neurobiology of "Forgotten Baby Syndrome."
He has a theory on how caring, competent parents can forget their children in the car.
Diamond's research led him to conclude that the reason is a failure of the memory system. There's a system called "prospective memory," which involves the intent to remember to complete tasks out of your ordinary routine, he wrote. And then there's a system called "habit memory," which is akin to being on autopilot.
The prospective system is what fails when a parent forgets a child in a car. Then habit takes over, Diamond wrote in his research. When it does, regardless of original intent, people complete routine tasks.
It's the same thing that happens when you are in a rush on the way to work and you put your coffee on top of the car roof, Fennell said. You get in, without thinking to take the coffee down, close the door, start to drive and the coffee flies.
It's not always that benign, though. And there is precedent for Diamond's conclusion.
The failure of prospective memory has resulted in other scenarios: plane crashes as a result of memory error, and incidents of police officers forgetting their guns were loaded, Diamond wrote.
A parent leaving a baby in a car is not carelessness; it's a failure of the memory system, he concluded.

Precautionary actions for parents
There are precautions parents can take.
KidsAndCars.org recommends making a habit of always opening the back door when parked, placing an essential item such as a purse or shoe in the back seat with your child and asking a care provider to contact you if your child is not on time.
The group also suggests keeping the car locked at all times so children can't enter on their own, teaching children to honk the car horn if they are locked in and never leaving keys within a child's reach.
