My UBAC was planned. We were living overseas in Japan, my husband was in the military. The local HB MW's there are not legaly allowed to attend VBAC. Given the choice between the military hospital, a Japanese hospital, or UC there was no choice for us! I was fairly certain that my VBAC would not be achieved at the MTF.
I did get prenatal care from the MTF, and we did use a doppler during the birth. Everything was great, it was an awesome birth. It was a big PIA afterwards, but it's the military. If you try to make them work outside the box they flounder!
We decided to get a MW this time as ideally we would have had one that time, I'm hoping it will be nice if the only work I have to do is the birthing. DH says he wants a MW so he can take a nap if he gets tired.
I'm a big fan of female support suring labor, so we thought we'd give a HBMW a go! But I have to give a big
up to UC. It was so empowering, and so right for us at the time. I have always been a believer in our inate birthing ability, but it's 100x's greater for me now.
