The worst part of summer is here, when children die slowly in searing-hot cars.
There were two one recent week, an 8-month-old in Virginia and a 16-month-old in Maryland.
Both deaths could have been prevented, if only we had the humility to accept a little help.
Technology exists to make it impossible for anyone to forget the baby in the back seat. We just don't use it.
Why? Because many people reject the notion that they could ever forget a kid. But it can happen to anyone in this age of distraction.
It has happened 19 times so far this year - and almost always, the script is the same. There's an otherwise solid, responsible parent who gets distracted on the way to work and forgets about the quiet, sleeping child strapped in the rear-facing, out-of-sight safety seat.
Scientists have tried to explain the way our memory lets this happen.
Our short-term memory can hold only a small number of line items, about seven. When that little brain basket is full - drop kid off, pick up birthday cake, e-mail boss about the project, call doctor, deliver report to Larry, pay car insurance, complete online training module, change water filter - one or two items fall out.
When the human brain clears out the less important things and realizes the most important task was the one that fell off the list, it's usually too late.
The Alexandria, Va., mother, Zoraida Magali Conde Hernandez, 32, went about her morning routine - day care, work, day care - only she forgot the first trip to day care and went straight to work, leaving the child inside a car for six hours while it was 90 degrees outside.
And she was immediately taken from Inova Alexandria Hospital, where she drove the child after she realized her fatal mistake, to the Arlington County Detention Center and charged with felony neglect.
She is the mother of five children. Of course she's got a ton of stuff floating around in her head on the way to work.
What happened to her could happen to any working parent. Read Gene Weingarten's Pulitzer-winning Washington Post magazine story on car-seat deaths in 2009, and you'll see what I mean.
Take a look at the statistics and see when this started happening - right after laws were passed that require kids to be in car seats in the back.
