I don't have toddlers or babies to worry about in the car. But even now with my two cats I have a way to prevent my greatest fears about them from coming true. My greatest fear is one of them being trapped in the dryer. So my method is I load the clothes, close the door and then make sure I locate them elsewhere before I start the dryer. It doesn't matter how tired I am or how rushed. That's my routine because it's a fear of mine. And as beloved as my little cats are, they aren't my children. This just doesn't make sense to me. I mean accidents happen but most of us are highly intune with protecting our kids and focused on their safety. And when something- like drowning or kidnapping or this- is a greatest fear of a parent, the likelihood of it happening because we suddenly were too busy or distracted to be afraid of it, seems impossible to me.
