I had a homebirth with just DH and two doulas present - technically my OB should have been there, but he couldn't make it as he was busy doing a cesarean in a hospital about half an hour from my home at the time I started feeling a bit pushy! He arrived just in time to help me deliver the placenta (which I found much more unpleasant than birthing the baby lol). I had already clamped and cut the cord myself!
However in fact I knew he wouldn't be there for the birth, it wasn't really premeditated, as such, but I was so happy and comfortable doing my own thing that I didn't actually get around to asking for him, it was my doula who saw that I was pushing and asked if I wanted him called. (We had discussed all this beforehand and this was a scenario we were all comfortable with). I felt really really calm and happy, and totally safe and comfortable. It was lovely. I should add though that I lived in a country where there are no midwives, and homebirth is quite rare, so that was not an option for me. I would not have liked the feeling that he was hanging about in the next room or whatever as then I would have felt under more pressure. However if midwives had been available I might have opted for that.
As a doula I attended homebirths where the OB was there and he was lovely, very hands off and respectful. But still there was a different atmosphere having a "medical" person there.
One client that I had (who also had a lotus birth) chose to freebirth - myself and another doula were on hand in case she needed us, but in the end she asked us to go and sit outside in the car as it was making her feel inhibited knowing we were downstairs! So this we did, and after her husband came out to tell us that the baby had been born we popped inside to make her some lunch and fold her washing!
Each to their own.
If I was having another baby in the UK, I think I would choose to have a homebirth with a private midwife, and I would ask her to be very hands off, and possibly not even in the room, I'd quite like it to be just me and DH and maybe my two DD's.
I'm pretty much with lulumama in that while I think most times birth is perfectly natural and safe, it is undeniable that there is some element of risk however small. Each of us will have a different view on what degree of risk we feel comfortable with. I think in my mind the "riskiest" part of birth is not the actual birth per se but the part immediately after, for example what if you had a PPH which is the most common cause of maternal mortality - although rare - would you have a birth kit with syntocinon etc? or at the very least a vial of shepherd's purse at hand? would you have an oxygen tank? Or would having even those basic things still be admitting an element of risk?
Anyway I'd be interested to hear how your thoughts evolve!
