Perhaps before you think about getting the procedure done you and your DH need to think about whether or not you would terminate if you found out your baby had Down syndrome. That is the real question. 1:350 at your age is a great 'number'. Any person, even a person with a number in the 1000's can be the 'one' who has the Down Sydrome child. If your answer to the question is that you would keep your baby no matter what then you don't even need to worry about having the procedure. If your answer is that you would make another decision then you need to think more about having the procedure done.

It is true that the risk has come down over the years and it is also true that the more experienced the person the better off you and your baby are in their hands.

For what it's worth - I have had both procedures and I had to make the hardest decision of my life in the end (with my first baby) and no-one should judge a women for the choices she may have to make.

I hope everything works out for the best. Use your instinct, that will take you far.
