I'm planning to HBAC too, and I think I'm making one of the most informed responsible decisons I've ever made. I can't think of a better way to have my baby than at home where I'm more in control of what happens. I also wanted a homebirth with my first, but was scared out of it, obviously wasn't as strong then and didn't know any better. If I had a homebirth last time I really think I may not have ended up having a ceaserean, with my personal circumstances.
To the comment regarding the MW transferring you during labour if there are signs of distress, do your research and really be aware of what they consider a reason to transfer. For example, my MW said to me that they would advice me to transfer if my waters had broken for 18hours and still no baby. However I've done the research and I would decline under those circumstances as I know you can go alot longer and it's still ok. There was a list of transfer reasons, only a couple I would agree to without arguement, the rest it would depend on the circumstances. It's a personal decision
My advice would be to hang around here (as there are a few of us due soon!) and do your research. I made sure I asked alot of questions here and found out alot of info I really did use when talking to my consultant and MW. My MW is fully supportive now, but wasn't when I first spoke about it to her, my consultant has 'strongly advised against it', but only on the grounds of uterine rupture (get used to hearing that mentioned ALOT lol), whereas the chances of that happening are 0.5%, its a bigger risk (1%) for cord prolapse for example but he's never once mentioned that?
I'm planning on having my daughter with me too as long as she and I am ok, so going to the hospital leaving her behind fills me with dread. Feels so much nicer knowing she will at least be around and there right away to welcome baby to the family. I can't wait, I'm so excited, so nervous, but so confident, such a mix of emotions but under the circumstances of being so pregnant think I'm doing ok
Good luck with everything
