Much better to have medical staff on board and deliver in a place where the baby can live. There are other birth defects that can be seen on ultrasound and prepared for as well.

^^^Yes that basically sums it up. I have a friend whose daughter was born with a severe heart condition which should have been caught on ultrasound, and because it wasn't, they were -very- lucky to catch it by fluke afterwards while the nurse was doing a check that isn't standard. Otherwise baby would likely have been sent home and become very sick very quickly, and probably not made it.
But yeah, mostly it stems from my desire to have a homebirth (and last time there was a chance of a UC), and wanting to know that I truly am a "low risk" pregnancy, and not in need of the higher interventions. I know not everyone worries about that, but for me, it's part of making sure that my plans are safe and in the best interests of all of us. I wouldn't feel comfortable homebirthing without a little bit more assurance that everything was alright with baby and I. And with the placenta too, yes it can move up, but it's very rare for it to move -down-, so if it's fine at 20 weeks, it's almost certain to be fine at the birth, kwim?
