Last week, a topic of conversation in my ygroups was someone's neighbor who accidentally dragged her child with their car. It was a classic accident involving an SUV's blind spot. A friend of mine once ran over his child's foot because of the same issue.
No matter how careful we are, accidents will happen. Still, that is no reason to be less vigilant about safety and security.
Have protocols in place at home, one that you implement strictly. Install mirrors and lighting where necessary or helpful. Invest in ATV Lights if you need them. Install gates, alarms, etc. and brief your household regularly about different kinds of hazards.
Once keeping safe is a habit, it will be easy.
