So sad that pregnant mothers and their husbands have to go through all the extra stress that this cult lays on them with the worry of refusing blood. I'm not sure why the doctors were so worried about the c-section and your friend needing blood or not surviving.
I had a c-section because I had preeclampsia and my blood tests showed my kidneys and liver were starting to shut down. Preeclampsia was the main cause of maternal death not so long ago before regular blood pressure checks and blood tests were implemented but there was no blood transfusion suggested, I just had saline.
Really sad your friends were put though this additional pain and stress because of a religious belief. I hope mother and baby are doing well.
