Hey Babyluv,

I had a think about this and here is what I think helped me get through 2 drug free (if you don't count gas) labours and births. Both babies were not in the right position so they were 'difficult' with about 3 hours of pushing. But hey I don't really know any different

I think not getting weighed down in the detail of your plan is important. such as "I want to walk around, be in the pool"... just go with what feels right at the time
I expected it to hurt a lot! I secretly hoped I would be one of those women who woke up one morning with a cramp and had the baby before I got out of bed, but in reality I knew it would hurt. This is important too. When you read lovely birth stories take heart but I think expecting pain is important.
Like you I DID NOT want intervention, and I think it was this sheer determination that got me through, With DD1 I was induced after my waters broke and I decided to choose my battles. I let them monitor me and out in an IV but I would have fought an unnecessary Caeser. My midwife was awesome too, kept everyone out of the room. I would probably fight the induction more now, having had a natural labour but who knows.
Tell yourself, outloud if it works for you (does for me), that you can;t wait to meet your baby. I do this a lot in labour adn I think it helps me remember the baby and forget the labour...I say "comeon baby I can't wait to meet you" or look at my husband and say "We're having a baby". That sounds silly written but it changes the focus from whats happenning to the magic that is about to happen. And especially for my pushing marathons, it makes me keep going.

Believe in yourself and your body! This is what it was made for! YOU CAN DO IT!
And also remember, that necessary C-sections save lives. I thinks its important to not demonise intervention completely, because you could end up feeling awful after birth. Again focus on the fact that you have made another human. That is awesome. You will be holding your baby in your arms... YOU CAN DO IT!
