I haven't had one yet, but currently planning a home birth with my first (34w) and have been with the home birth team since my booking in appointment. I would do it again purely for the experience I've had so far.
You meet the home birth midwife team several times and get to know them, and them you, which they say is really important to understand what is 'normal' for you so they can assess you better in labour. There is a lot of evidence for the benefits on mothers, babies and childbirth outcomes simply from continuity of care. The team I have are brilliant and regularly organized meet ups with other mums planning home births, or interested in the idea, where new mums who have just been through it come along and talk through their experience, which we have found invaluable.
You get all you appointments (except scans) at home! No waiting around for hours in overheated hospital waiting rooms. They come to you, can take blood samples, blood pressure, give injections in the comfort of your home, do the doppler with you lying on the sofa... It's great! I had to go to clinic at the hospital this week and reminded how horrid it is there, especially being around lots of very unwell people and increased risk of infection (also had to wait 45mins to give a blood sample
)
You will also get one-to-one care during established labour, and two-to-one care during birth. It means you are fully, continuously supported in a way wards can't manage, and they will be able to spot any irregularities from a mile off.
The way I look at it, even if things don't end up going quite to plan, I get this fantastic level of one to one care throughout my pregnancy, and I get to labour for as long as possible at home, which for me is where I feel most safe and comfortable. There is lots of evidence to corroborate that giving birth at home hugely reduces risk of unnecessary interventions, which could lead to long term pain or issues for the mother, birth trauma, risk of infection etc.
It's worth knowing all the facts - the Birthplace Study, a large UK research study which followed women giving birth from 2008-2010, found that for women having a first baby at home there was increased risk to the baby, with 9.3 adverse perinatal outcomes per 1000 planned home births compared to 5.3 per 1000 planned births in an obstetrics unit. However the risk is still very low generally and birth is very safe in the UK, especially if you are low risk and live close to hospital. Also in my Borough over 60% of home birthers end up transferring to hospital for a variety of reasons, but mostly due to prolonged labour (the mother is exhausted and feels she needs more assistance) and requests for more powerful pain management (you can only have gas and air and Tens machine if giving birth at home).
For me, the benefits massively outweigh the risks and I feel safe, happy, supported (and... excited?!) about my plan to birth from home.
