i dont want to pass judgement on these people. Having recently had a baby girl and now understood the amount of love and protection a parent feels for their child, im sure in their hearts they feel it is the right choice.
This couple seem to be coping with their childs disability when many would have given up.
As with most 'advances' in medicine, ethics are coming more and more complicated. I think what is the most important thing to bare in mind is that it is the child who must come first not the parents.
