You did make the right decision! I'm so sorry that you had to hear that crap. And from you baby's grandma no less! Do they even understand the impact of telling a mother (or father?) they should have let their little one die. You could have countered by asking them what kind of god would destroy this innocent child forever for a decision her parent made. I don't think it would have broke through the cognitive dissonance, but you'd have had the satisfaction of voicing it.
And Welcome! Is your story here? Have you introduced yourself? Did the blood issue lead to you leaving the WT?
