mossgood... I would feel bad if my children or grandchildren had any kind of an accident.. I tell them not to get into the knives or touch the hot stove or play with matches or jump in large bodies of water before they can swim or stay out of the street...
I also teach them safe gun handling or... if they are too young.. they simply will not have the gun available any more than anything else dangerous... it will be up out of their reach because they may club themselves with it.. they will not be able to get it down and not strong enough to work the action... as they get older and curious I will show them the gun and allow them to handle it under my supervision and tell them not to touch without supervision.. Latter, I will take them out shooting and teach them safe gun handling if they are interested.
None of these precautions will guarentee that they wonm't burn the house down or drownm or get run over or shoot themselves and I will feel equally bad if any of those things happen.
it's not really that complex.
