I am just going to share my experience. I have two dds. One who was born in 2002 and one born last year.
With dd1 - they picked up her heart defect and told me that she would 99.999999999999 % also have down syndrome. It was very very very rare for people to have her heart defect and not have down syndrome. I was very lucky - the cardiologist told dh and I that if it would not make a difference - don't have an amnio - even though it would have been Prof Kypriades doing it at the harris birthright trust. We had already decided dd would be born when we thought she had a different type of heart defect. Whilst we knew having a child with ds would be hard - bloody hard sometimes - we also had positive experiences to draw on in dealing with down syndrome.
After my dd1 was born and even now almost three years later - the first thing any new medical person asks is - did I know she would be born with down syndrome. When I say yes - they have no reply. Some seem surprised that we chose to have a child with ds. To us - we chose to have a child. The only antenatal testing I had was a gtt and the ultrasounds.
Even when we were enduring her two open heart surgeries and all the stress that came with the recovery and the therapy etc. We do not regret our decision to have her. Even when she is being a typical 2 yo and throwing a tantrum with the best of them. SOme days are hard, some are heartbreaking and others just blow your mind and make you realise what really is important in life.
Fast forward 2 years - I am pregnant again. The first consultation I have with a doctor in the UK - he starts to list the referrals he will be making - from a fetal cardiac scan to an amnio etc because I will want to know. I told him that I was not having any of those tests. He then asked me why I did not want to know about this baby and in a most patronising tone telling me that my risk is automatically increased compared to other women of my age of having another child with ds. This is all with dd1 sitting in the consultation room. I then told him we chose to have dd knowing that she had down syndrome. He then went on about her heart defect. I finally had to stop him and tell him that dd had a heart defect because she had down syndrome and there was no reason to suspect this child would have a heart defect.
When we went for the dating scan dd1 was with us and the sonographer asked if I would be having a nuchal fold scan - I said no ... to which she proceeded to go and look at and measure the nuchal fold anyway and tell me it was in the 'normal' range. I was speechless. DH just glared at her. She smiled nicely thinking she was doing us a favour.
I then had the midwife call me to set up my blood tests. I told her I would not be having any - to which I got a talk about how I should want to know if there was anything wrong with this child etc. I then told her that we chose to have dd downsyndrome and all. She then went on again. I had to finally butt in and tell her that we were not interested and I did not need her services. Largely as we were emigrating to Australia.
We arrive in Australia in time for a 20 week scan which picks up a very soft marker for down syndrome. We spoke with a genetic counsellor as to what that meant to our 'risk'. She told us and then suggested that we had the option of an amnio. I told her we did not with dd1 and so would not with this child. She totally understood.
The pushing for testing began again with a registrar who wanted to know why I was not having an amnio, why did I not have bloods done, nuchal fold etc. Again dd1 is in the room.
There have been medical professionals that could push people to do things with the manner and the way they choose to present things. Am positive - had I not been the single minded outspoken forward woman that I am - I probably would have felt compelled to have tests done. BUT I did some research and opted for very little testing - with no regrets. I know have two beautiful daughters who have enriched my life in ways I never thought possible.
Sadly the statistics show for example in 2002 when dd1 was born - more children with down syndrome were aborted than were born.
I have come across a number of adults with down syndrome who live fabulous lives - they marry, live independantly, work, socialise - all the things we do.
Sorry I realise this is a ramble but maybe you can take something from my story.
