Purest I can actually offer you advice because im going through a matter very similar...
In our genes we have cerebal palsy and muscular dystrophy, my sister and my father have been affected by these dieseases since they were born unfortunatly both diesease affect males over females.
I had my children, knowing there could always be a possibility of these dieseases attacking them but my sister and father lead more than normal lives. My father doesn not tell anyone he is disabled fo the fact he does not want to be treated differently but will tell ppl after. I think as long as that person is treated normal they will feel and act normal but it is up to the parents to teach them that moral!
However, I feel that if a child so severly disabled they will never be able to reap the benefits of life/ sit there and do nothing/unable to comprehend anything then preferably a mother should terminate unless they can handle the sitiuation and not ask of society to take care of them.
This is my opinion but I will never judge force my opinions on someone, life should be made equal to everyone but to someone who will never be able to enjoy it why bring them to life!
