I was told with my first son that he had a thick neck and that there was a possibility of Downs but because the only reason they wanted to do a amnio was to see if he had it or not I chose not to because he was my baby and it didnt matter to me, I was going to love him no matter what. I am glad that I didnt make a big deal of this because this Aug. he will be turning 7 yrs old and he is doing great, no Downs. I wish you luck in your pregnancy and I hope that all goes well.
