I’ll pray for her to have a baby, God’s way. May IVF not be necessary this time.
I've read all the arguments about spontaneous abortions, fertilized eggs that don't implant, tubal pregnancies, but those did not involve conscious choice. That is what makes the difference to me. Others are free to think and do as they will, but I kind of mourn the lost ones, may sound silly.
I fear much worse lies ahead in the way of new cutting edge technologies which will involve more moral choices that cannot be foreseen now.
Let God be her judge. As my mother used to say, and she wasn't outwardly very religious, "there but by the grace of God go I." which I have invoked in my own life many times.
There must have been a few infertile couples when I was growing up, but it seems more widespread now. I've heard of couples who couldn't conceive, adopted a child, then conceived. My mother was 37 when she had me, her first (as far as I know) and my sister at 39.
I do believe prayers to conceive a child the natural way are sometimes answered. Also I think of Sarah in the OT and Elizabeth in the new.
