If you knew people in real life, who had lost a child to accidental death that could, with hindsight, have easily been avoided would you berate them?
I imagine those self righteous posters who persistently bash bereaved parents as indignant hens, clucking and squalking their indignance at human mistakes.
There but for the grace of God go any of us. Maybe we would not let our dcs near a quad bike, a rotweiller, or leave them alone - but most of us let them swim in the sea when on holidays, or play close to a resort pool, or climb on the furniture, ride bicycles on roads, play rugby, potentially have access to the medicine cupboard...
I almost caused a road accident this morning, when tired on a very long journey - had my foolishness caused injury or death I would never have forgiven myself. I had driven past a potential rest stop at the half-way mark because I was impatient to reach my destination, that was a reckless mistake and one I won't make again. The parents of that unfortunate little girl were not so lucky.
