I have been reading this thread and now I feel I have to make comment.
I too have been given a high risk of down's syndrome with my pregnancy and have had to face what the poor lady in question is facing. Before making my own choices about further testing I did look into what it means to have have a child with down's syndrome and talked the whole thing through throughly with my partner about what we felt would be gained or risked by testing and what our feelings would be on the results. The choices we made, not to have further testing, were difficult and personal to us. I am however glad that we had the initial tests which gave us that choice to make.
I realise that what has been said on this board had clearly touched nerves with many people, esp those who already have children with DS, but I think it needs to be clear that the lady in question here has her own circumstances, opinions and feelings which none of us are aware of.
One thing I am sure of is that this is a difficult and upsetting time for anyone, whatever they decide to do and the lady needs advice and support in whatever she chooses, which certainly seems to be lacking from her healthcare providers if her friend is on here looking for answers. She does not need comments on how she must just be ill-informed if her choice is not to go ahead with the pregnancy.
People terminate pregnancies for lots and lots of reasons, and I for one would not tell anyone what their choices should be or what they should base them on.
My own choice is that if our baby has DS, then so be it, it's just who my baby is and I see no reason why that's a big problem, but that's my choice to make and the person here has her own choice to make.
On a further point I also want to say that I think comments on here warning against ante-natal testing are also personal choice, but it needs to be pointed out that testing can reveal problems that can be treated before the baby is born and give the best chance possible to the child, and for that reason I would always go ahead with the non-invasive tests. A friend of mine had no AN tests and had a son with Noonans syndrome and lived for just a year. She always regretted not having the tests done which could have given advance warning that someone was wrong.
