I have two young sons, both with a rare genetic disorder which means they will not survive beyond their 20s. My husband and I want to try for a third child—this time with genetic counseling—as the idea of being bereft of children in our 40s is far too devastating for us. But we wonder at the ethical implication of having a child who will lose both her siblings while in her teens, as well as growing up with parents who will be focused on caring for two highly dependent, special needs children. Is what we’re contemplating totally selfish?
I am torn and in need of an objective, third-person perspective.
