Heather,
Just wanted to say I understand your dilemna. It seems to me that your husband put you in a terrible spot, and you should do everything within your power to force him not to do it again.
I admire your stance for your children, and I strongly suggest you take some legal steps to ensure your wishes are carried out, and they recieve blood in case of emergency before you get to the scene. If it happened that your husband arrived first, and did not allow it, you could lose a child to their stupid policy.
Stay strong,
Happyout
