Hello
Lots of good replies here but thought I'd add my experience too
I had a planned home waterbirth with my DD nearly a year ago (where did that go!??)
I laboured from 6pm on sat when it started quite fast and hard to 10am on sunday morning when DD was born. I got in the pool at about 1am on the sunday morning.
For me it was absolutely what I wanted and it was hard to know how different it was to land birth as it was my first, but I know when I came out of the water for examinations and to get speed it up (slowed down at about 5 or 6am as I was so tired) it was excruciating by comparison. Getting back in was bliss.
As someone said it is amazing being able to lift your baby out of the water yourself and see him/her for the first time yourself and not via the midwife. I will never forget the sight of my DD's big eyes looking right up and me.
I had G&A but it made me really sick, so didnt use much. My DD was nearly 11lbs so it was quite hard going labour. I dont think I would have done it with about 10 puffs of G&A only if I'd not had the water.
I used natal hypnotherapy cds for relaxation before and the techniques were great in early labour for getting through the contractions.
Easy to say but try not to worry about it too much- there is little you can do to change how it goes - but try to ensure that you are rested and relaxed.
If you need to channel your nervous energy read as much as you can about the first month or so etc and breastfeeding. I thought it was a case a of putting DD to the breast and she'd do the rest but it wasnt and I wish I'd been better prepared in my head.
GOod luck.
PS sorry for essay. Seems most woman loves to talk about their birth experience
