My mom was told that my sister would likely have down syndrome. They even asked if she wanted to "keep" the baby. My mom said yes and they held on until they could perform an amniocentisis (sp?) test. This is where they take a long needle through the abdomen and take out some of the amniotic fluid and run tests. After they did this they determined that the baby was normal. So hang in there sometime this scare can be a false indicator of DS.
Best wishes and health!
