After some excellent comments on my last post, I wanted to clarify something- I most certainly understand why people do testing, even if they wouldn't terminate the pregnancy. Testing gives you more time to process. It give you time to prepare, mentally and emotionally. There's definitely nothing wrong with wanting to know ahead of time. In fact, before Daniel was born I wondered if people who were surprised by babies with Down syndrome (or some other diagnosis) wished they had done the tests.
I was serious when I said that I'd thought about it a lot. I considered how things would have been different if we'd known before he was born. I thought about how I might have felt about a prenatal diagnosis (obviously I thought about that, since that's what I wrote about last time.) And it's only now, on the other side of things, that I'm completely sure not testing was the right choice for us.
And now I'll stop talking about this.
