I have not had one personally but a few years ago I talked another close ex JW relative into having one after a difficult child birth. Although she was no longer a JW at that time she was absolutely terified of the consequences of having a transfusion, mainly of upsetting JW relatives and she was in a state of panic. I calmed her and persuaded her that it was more important for her to be around for her lovely new baby and that the JW relatives would never know anything about it unless someone told them. Me and her husband between us talked her into it. I sat by her bedside and watched her skin change from a deathly greyish white to a healthy pink as the transfusion started to take effect. She was up and about within a couple of days and soon recovered enough to care for her lovely little baby. If anyone is to blame for her having a transfusion it is me for talking her into it, and I would do it again in a heartbeat.
I agree serein, no one should be put in that situation, especially new mothers with tiny new lives to care for. Your babies came first which is only right!
My love and best wishes to you and your babies.
