I like to think I would never get distracted while my child is near a pond, but nobody is perfect, so it could happen.
Bull. The "it could happen to anyone" mentality makes it seem like it's unavoidable when it's not.
Anytime my toddler is near water she has my undivided attention. The phone is put down and I make sure she's properly supervised in case I need to quickly scoop her up out of the kiddie pool. She's never outside without me there. Yes, I've checked my phone while she's in the back yard playing but she's always in my peripheral (and there's not much she can hurt herself on).
Same goes for near the road. My child has darted towards the road and I have been right on her heals. In parking lots it's strict hand holding or I carry her.
This isn't like a party at a friend's house and her kid slipped out the door. This pond was on her own property and she didn't fill it in, build a fence, or keep a sharp eye on him knowing there was a drowning hazard.
This "losing a child is punishment enough" mentality is for people who actually care about their children enough to take reasonable precautions for them. Not idiots who let their toddler run outside with no supervision or hold their baby while driving.
