For us, it wasn't just my decision but my husband's too. We had the NT scan at 13 weeks.

He wanted to know that the baby was low risk for DS etc. He would have wanted to terminate the pregnancy. He was really frightened about the possibility of us having a disabled child, much more so than I am, and I guess I realised it was important to respect his worries about it.

I also wanted to know (would want to prepare myself for the arrival of a DS baby), but I am pretty sure that I would not have wanted to terminate the pregnancy. Not a nice situation to contemplate, disagreeing with my husband about something like that. I think my decision would prevail, but not sure what that would do to our marriage.

Anyway, in the end, knowing that the risk of DS is low anyway (and having a good understanding of statistics myself - I'm not easily scared by risk factors for stuff), I decided that the chance for both of us, especially my husband, to bond with our baby by seeing her more clearly looking like a little human was of such value that it was worth the small risk of finding out a stressful result and then having to wait for an amnio. This while pregnancy thing is so concrete to me and so abstract to him - he doesn't feel the kicks and movements, he doesn't experience the host of physical effects it has on me. So to him the baby is less important, less real, than she is to me. I think anything that gives my husband a greater opportunity to bond with the baby before she arrives is a good thing.
