I know I will have several. I feel that are needed, maybe not for everyone but for me they are.
With DD I should have had more, it would have prevented a horrible birth and her ending up in the NICU have having a seizure.
Also DH had a heart defect, which we found out is genetic, not from him being early as MIL claims. (he was 2 weeks "early") so we need to know about that too.
I won't have any 3D or 4D though, and I try to avoid doppler though. The waves from a doppler are more intense 'cause they're steady whereas with an ultrasound they are intermittent. Trixie would fight to get away from the doppler. I hated that I had to be continually monitored when I was in labour with her, poor baby, everything else was going on and that!
Anyhow that's my take on it. How fun that we have such a variety of opinions and plans for them!
Oh I do plan to HBAC if I am pregnant with twins or less. (which I should be, but there were 7 eggs and an IUI)
