Yay! I think A homebirth is fab! If you do the hypnobirthing I think it will really help your oh be ok with the idea when he hears about all the benefits etc and the increased chance of interventions and stuff in hospital. Also if he likes doing research and trading around a topic get him to look on homebirth.org for information :)
Ps I honestly didn't feel as if I was in lots of pain, the contractions felt strong but it was totally managable and the best experience I've ever had. There's no reason why it would be any different for you!
It's a long way off yet anyway! Gauge the response of the midwife when you mention homebirths- mine were very supportive but if they are not you can always change. You can get a free, independent midwife now too- I'll find the link....
