Ok, so I'm a little worried about my little guy.  We have to get another U/S from a specialist because he has a CP Cyst on his brain which is harmless on its own, but is a soft marker for Downs.  Since my blood tests for chromosomal abnormalities all came back low risk, she said it's probably nothing and will most likely go away on its own but I can't help but worry.  Does anyone else have any experience with this?  I'm hoping for some positive outcomes.   Thanks!
