Discovering disability

If you were expecting a child but discovered it was going to be severely disabled what would you do? A disability is a massive thing to cope with and can destroy families with medical bills, strain and a constant tie to the child which will never lift. Of course some people are against abortion, in some cases for religious reasons which I completely understand, however I think we have to consider the quality of life for the child. Operations, discrimination and other struggles may form their life and I don't think anyone would wish that upon their own child. A controversial issue for some serious thinking about.
