Seeker, my POV is coming from myself as an 11yr old who had been looking after my siblings overnight, in the holidays and as and when mum went out, from a younger age, about 8-9yrs old.
At the time of my sisters serious accident, i was quite accomplished at looking after younger children, especially babies, i could cook a simple meal, out of necessity, mum wasn't a great cook, or egar to do it daily.
I also walked 2 of my siblings to and from school, crossing main roads and make sure they were up, dressed, and had lunch to take.
I was also the night nanny a lot (4 of us shared a room )learnt to make bottles and change nappies in the dark quite quickly, and my weekends consisted of cleaning the house top to bottom with the promise of swimming money.
I wasn't a childish 11yr old with no experience, yet that accident still happened.
There were other accidents, none as serious as this, but still, my sister lost parts of her hand due to that day.
You see, it doesn't matter how well prepared someone is, an accident can happen when you have taken as many precautions that is reasonable, it is an unforseen event, that can and does sometimes have tragic consequences, now i personally think that a mature adult has more life skills to decide the most appropriate way to deal with a childs injury, they probably will also have better skills to deal with the inevitable guilt that is experienced when a child in you care ends up getting hurt.
I still find myself trying to make it up to my sister, and she has nerve pain in that hand, when it gets cold and i see a fb status about how she's had to take a day off work because it hurts so much, i still get upset over it.
