Granted that the anomaly scan does not show Chromosomal abnormalities but I do feel that it's being implied that your either irresponsible for not finding out or that you don't love your love if you don't continue with the pregnancy....
I think there are varying degrees of abnormalities and I personally am glad not to have found out, obviously I don't want to bring a child into this world that won't survive but at the same time any of us could give birth to a healthy baby and the SIDs happens....
I agree with babym - My sister had bowl problems, cleft palate, heart murmer and deaf- advice abort?! Her bowl problems have improved with age, her cleft palate was operated and the murmur closed over years, she had a bone anchored hearing implant and throughout the first 12 years of her life 14 operations, now she has a degree in accountancy a great Job her speech is fine and she has an amazing life- unfortunately I know this is unlikely to be the case with all situations and my sisters problems were physical.
I believe we all make the best decision we can for our little ones sometimes that may be to limit pain & suffering in the way we see best.
As for downs syndrome - it is not always life threatening and like So_hopeful I personally would feel so incredibly blessed to have that child in my life regardless of how hard that life could potentially be.
Again we all make the best decisions we can for our babies with the knowledge we have available - like shoes one size does not fit all
Good luck to all awaiting results xxxxx
