Hello Pobletsmum, I am a new Doula and a VBACer. I always say that 90% of the birth is the work done before hand, in preparing your Birth Preferences, going over your previous birth (if applicable), instilling confidence by helping the mum to learn about normal birth and that she is actually very well designed to do this!
I lend books from my library of wonderful authors, I give email and phone contact as much as is wanted. I point mums in the direction of information to help them make informed decisions. And I can attend at antenatal appts with women if required. This is what Doula's do!
Then at the birth we are there in whatever way the mum wants us, maybe just there while dh is the physical support, or being more hands on while dh does manly stuff like filling pool (if at home). Doulas help to remind you of your Preferences if decisions require to be made and can speak up for you as your advocate if you do not wish to be disturbed.
We DON'T make clinical decisions or give advice.
The worst thing for childbirth is fear, so you need to do some work now to educate yourself about birth and realise that you can do this.
How much intervention was there at your first birth? All too often, I'm afraid, intervention is the norm and this tends to lead to more trauma. Intervention is not always necessary but how are we to know this before hand? I was so naive at my first.... and even to some extent at my VBAC, which was assisted by forceps. I feel cheated and a fraud because having a spinal meant that I did not feel the birth, felt somewhat removed from it and also have another scar to add to the one on my bikini line .
Definitely call a few Doulas in your area and see how you get on. Dh's tend to find them so helpful as they are too emotionally involved in the birth and so can't be as strong for their partners as they would have liked. To have encouragement that they are doing the right thing etc can be such a bonus.
Have you done any reading into normal birth yet? Ina May Gaskin, Dr Sarah Buckley, Pam England, are a few to start with,
gotta go, hope that's enough to start with!
