NEW YORK (WABC) --It's been happening more frequently, children left behind in hot cars, and the consequences are deadly and heartbreaking.
Tuesday in Ridgefield, Connecticut, a 15-month old died after being left in a hot car when his father went to work.
That death yesterday brings the total to 16 deaths this year and the summer is just getting started.
Most of these deaths are completely unintentional, good parents who are just busy and distracted.
Never leave your child in a closed car, not for a minute, not even to run in and get groceries.
A child's body temperature rises three to five times faster than an adult and a car quickly becomes an oven.
The outside temperature Wednesday afternoon was 89.9 degrees. In our unofficial experiment we watched it go up to 105.8 degrees in just 15 minutes.
"For parents to think this couldn't happen to them is an enormous mistake," said Sue Auriemma, the Vice President of KidsAndCars.org.
A rear facing car seat looks the same whether your baby is in it or not making it easier to forget.
Some new high tech car seats have an app that warns you.
One man invented the child in car alert device. It beeps when you turn the car off. If you still forget your child, it then starts honking.
Andrew Schuller won a contest for his invention
"As you're getting in, you attach it to car handle," said Andrew Schuller the creator of the EZ Baby Saver.
The EZ Baby Saver band blocks you from getting out as a reminder.
The shoe trick also went viral. It sounds strange, but after the child is in the seat, put your left shoe in the back seat, so even if you forget, you'll remember when you step out.
As the vice president of KidsAndCars.org Sue Auriemma demonstrated two more low tech prevention tips.
"Leave your purse in the back, and a stuffed animal in the front," Auriemma said.
The bottom line is to create some reminder for yourself every time.
People often think that leaving the windows open a little bit helps, but that's a myth. It does not significantly slow the heating process or impact the overall temperature.
