Letting a 5yo wander off unsupervised to a large body of water is pretty dumb.

I wonder if people who are down-voting you actually have children. I even know someone who's kid just died in a pool when no one was watching... My kids almost drowned themselves multiple times when they were below 5 yr old and they are trained to swim... My brother fell into a pool when he was little, and had to be saved... the list goes on and on... edit: Apparently it's the leading cause of death for 1-4 year olds...

I agree. The word "pond" is what immediately got my attention.
