No matter what, I have never left my kids in the car......unless, like Heather, it is a station with the attendant right there.
Most of our children were over 2 when they came to us...regardless...if I had errands to run, it was done when dad was available to watch them.....or, I had a train
(thus, the screen name).
When we did have a baby, with all the info out there, no way was I leaving that young man out of my sight.
More and more, this world is unsafe........sadly, even in our own homes now.
Used to watch a child that decided to take the car for a drive....the keys were in her reach, she took them (she was home with parents at the time), started the car, put it in gear......and rolled it down their 100 yard drive......luckily, just missing a tree. Totaled the car.....she was 3 years old!
My keys aren't even where the kids can get them, after that!
