So sad. As a parent, grandparent, I can imagine the grief.
Years ago I raced out of Lakeside in Cleveland. Over the course a very few years, three young people were lost
to drowning. Since the floatation for 14 years & under/ on dock
or boat rule
was instituted, no subsequent losses. At least twice one of my own toddlers fell in. Sometimes you don't eve hear the splash. Fortunately, we only needed to deal with wet clothes.
Its good to note along any dock area where the safety
ladders are and point them out to your kids
& guests. What is noteworthy is the number of public places without any ladders.
