Bem,
Bless you for donating your Rh neg blood! I can't do so anymore, and I regret it, as donating blood was one of my first acts after gaining independence from the WTS.
I, too, am Rh neg and had the Rhogam decision to make with my children. I wasn't yet a baptized witness, but with my last pregnancy I was already dedicated. So it was a very tough decision to make as I had been unaware that Rhogam was a blood product! Only when I mentioned to the OB/GYN that I would refuse blood were there to be complications was I let in on the fact that I had already chosen to protect my two previous unborns by using a blood fraction. I elected to take the Rhogam, feeling it was unfair to my husband and unborn child to put the baby at risk because of my newfound "beliefs." But I DID opt not to take the post-partum Rhogam, so I made CERTAIN that we did not want any more children. If I were to become pregnant again, I would have faced the same sad and scary situation that your cousin is now facing.
What I don't understand is WHY she chose as she did (with her Mom's guidance/support?). What positively INFURIATED me, and nearly made me leave Jehovah's Witnesses less than two years after my baptism, was the June 1990 (can't remember if it was in a WT or an Awake, but I think the 6/15 WT) article saying that blood fractions were now allowed. Your cousin did NOT have to put future pregnancies at risk according to that article's "new light." Taking Rhogam, like other anti-venom or immune-boosting treatments, is a conscious matter. I FREAKED out and confronted the CO when he arrived shortly thereafter asking him why something forbidden was now okay? His response was, "Because the Society says so." And he dismissed me and moved on!!! I should've left right then, but it took me almost another decade to extricate myself. Silly me!
I'm sorry for your worry over your cousin and her developing child.
