I responded already. Truly sad, but I said the thing to do is love the child and take care of the child till it passes on it's on. A person who is breathing, eating, but without a brain, is still a loved child of God.
I made my comments there, too, after yours. I just never understood how there could be a question. It never entered our minds. We also never planned, nor had the occasion to use extraordinary means to keep our son alive.
