Jim,
I could'nt agree more with Dr. Hill. We had a chance of 1/30 of a
child with Down's. (Not as a result of a triple screening test, but
because of my age, 43 then and 44 at delivery). Still the doctor told
us to just view the amnio as a reassurance that everything was OK. I
had the amnio (and it was'nt a bit as terrible as I had expected it to
be!) and after three weeks we got the news that the baby was a healthy
girl! Ever since I have been able to enjoy my pregnancy even more, it
really takes a load off your shoulders.
Good luck to you and your wife, and I hope you will both enjoy this
pregnancy!
