I agree w/most of you: Once we have a child, I'm 99% certain that I will feel it's more important to save the child than to save MrBecca if I HAVE to choose, because MrBecca is more likely to be capable of saving himself and because the child is our future.
But we have strong feelings in the opposite direction about a somewhat different version of this dilemma: When I am pregnant/giving birth, if MrBecca has to make a choice between saving my life and saving the baby, we both think he should choose me. The fact that we could then have another baby later is way low on our list of reasons why. More important to us is that I already have a whole life and a lot of people who love me (including him!) so that my death would impact many people, whereas the baby would have only a few people just beginning to love it and would not really have loved anyone back. We would of course be devastated by the loss of our child (which is the main reason being able to have another baby later isn't much consolation) but not nearly so much as he would be devastated by losing me. Plus, he would then have to take care of a new baby all alone and would be in no condition to do so.
If we already had an older child, that would reinforce our choice, because it would be less devastating to the child to lose a sibling she'd never known than to lose her mother.
Once the child is born and we really get to know and love it, then it's a whole different story. That's how we feel. How about the rest of you?
