When I was a teenager my best friends little brother (baby) died because he was refused a blood transfussion. It really bothered me even though I thought they did the right thing.
Now that I'm out I was talking to my wife about it and the whole blood thing and came to the realization that they did it just to save themselves.
Think about it. If you allow your child to have a blood transfusion, who is God going to blame? You or the child?
Obviously he will blame you. Even the society says that it's not the child's fault if the parents allow a blood transfusion.
So in my opinion they are just selfishly saving themselves.
I for one would gladly die to save my child. And if God wants to kill me for saving my child's life, then so be it.
P.S. I don't have any children yet, and I totally disagree with the blood policy.
