Perhaps my comment will be silly. Can you just put a child in the passenger seat in front of the car?

We've altered natural selection by putting warning signs and labels on the obvious. 50 years ago those folks that need those signs would not have lived long enough to reproduce. The gene pool is getting dangerously shallow.

Look, I'm not saying people should have to have a license to be parents.

I'm just saying I really don't like the people who couldn't get one, BEING parents.

It's not that people don't value their children..it's a problem remembering them when people change their memorized routines.

Maybe you don't always take your child shopping with you, so there's no established habit, but with the cellphone, people likely check on it constantly without thinking, so putting the cell phone in the back with the child is a GOOD idea, since it forces the person to think about what they're doing.

Stupidity has no bounds.

freaking amazing, sadly so true.

A child died in Montreal under those circumstances just this past week.

what a horrible death and how guilty would you feel as a parent if it actually happened to you. I understand the word valuable in the post is stupid but whatever mechanism that can prevent this is something good in my book.
