Quoting Robbie's Incubator:" Your nine-year-old daughter, Emily, is dying. She has a life-threatening disease (Leukaemia or Lymphoma ... [snip!] ... the baby early and risk the baby's health to save Emily, or Emily could possibly die in less than a week. What do you do?"
Well if I put myself in the situation with it being my daughter IRL then I would deliver the baby (at a hospital like Sick Kids so it had the best possible chance at survival) as horrible as that may make me. The bond that I have with my daughter would be much more then my bond with the baby I would have in my womb.. Especially if it was created basically solely for the purpose of saving my living child.
