No Witness needs to worry about blood for their child anymore.
The Society has quietly changed that. There is a form now for parents that basically says they dont want blood for religious reasons but will leave it in the Dr's. hands.
This originated in Canada. An ethics committee which included Br's from the Canadian branch worked on the form. Canadian newspapers carried the story.
I first learned of this because of a baby in a local hall needing a complex surgery.
We had a thread here somewhere that mentioned the name of the form. Sorry I cant remember it.
