JD, I think you and your DH have such an awesome attitude, what a lucky little bubba to have such great parents.
We had our NF scan with DD because we wanted to see her (naughty, I know) but I think with the next baby we probably won't.
I used to babysit a Downs girl, she was such a neat kid and out of all the kids I babysat for in my youth, she was my absolute favourite.
