She will probably need a C-section when the time comes, but that's fairly routine obstetrics.
I would not consider requiring surgical intervention to prevent death of mother and/or baby, safely to term
Despite Northstar's histrionics I do not think abortion should be the immediate choice or is necessarily the best choice, family is already in the realm of no quick, easy, and safe choices. Any choice in the case of a pregnant 10 year old is going to be emotionally painful.
