I'm not a HBer but I just wanted to wish you well and give you a big thumbs up for getting yourself prepared mentally.

I birthed my sons naturally, without the need for pain relief and what gave me an edge (I think) was being fully educated about the actual process of birthing a baby (ie/ why we feel contractions and what purpose they have etc), and being prepared (mentally) to birth the way I wanted.

I imagine you'll get some great tips from those BB mums who had wonderful HB.

Good luck!
