I guess the problem for parents is, when a disability is identified it can be a broad spectrum.
Most people have met and known high functioning downs syndrome and disabled people, who are happy, well adjusted, reasonably integrated members of society - most aren’t exposed to very low functioning though, these are profoundly disabled people who can have appalling quality of life and often have other health issues as well. Of course you’d love your child no matter what.
I knew a woman who had two children, the younger of whom was profoundly disabled. By the time her youngest was 7 she was faced with a heartbreaking decision, the child was completely disconnected and was getting stronger and more violent by the day. She needed to be put in care, which meant being institutionalised - just a devastating choice which was really no choice at all.
This woman ended up suiciding - an absolute tragedy, leaving the younger child in care and the older dealing with the loss of her mother.
This awful outcome made me really think about my fortitude and capabilities when I found out I was pregnant, I’d love to say that I would go through with it no matter what but the truth is that I don’t know what I would have done if there was a problem, I’m so glad that I didn’t have to make that decision.
I also know that these tests are not 100% accurate, unless they can prove negligence they’re pretty screwed, if it was negligence then it’s completely reasonable for them to be compensated for the additional cost of care.
That Arizona thing scares the shit out of me!
ETA - It took me 2+ years to get pregnant, lots of intervention, I’m 36 and I still got the non-invasive testing done and would seriously have considered my options if the results hadn’t been so favourable.
