Can I just point one thing out with booking a home birth, YOU DO NOT have to birth at home. Though the choice will be entirely yours and open when you do book one and decide you want to stay home or home longer whilst in labour... If at any point you don't feel secure at home and feel like you'd be better off in hospital you're allowed to go there, if at any point the midwife feels like you're better off in hospital they will transfer you!
And when you do go in labour and at that point you think, I want to go in hospital you can still go and you don't need to phone the midwife to come out!
The nice thing about it is that when you're booked at home, they will come out to you. If you are in labour from that point when they arrive at your home they will look after you and assess you regardless where you want to birth from then on. They don't let you stay home if they think your baby needs close monitoring.
Pools can be hired instead of bought and only fresh lining has to be purchased.
Trust me, you don't give two hoots about how much noise you make when you're in labour even when you're at home!
And another thing, at hospital there's a bigger chance for intervention, that chance increases with stronger painkillers like the epidural because it stops your ability to move around and get up or push the baby out.
They can bring gas and air, they listen to the heart beat at home so if any point that makes them worried again you'd be sent into hospital ect.
Cheap own brand shower curtains are great as a cover for all the messy bits!
There's home birthing groups who have people in it who have experience fighting for a homebirth in special situations when it's not the first pregnancy that you can find on facebook.
Hope that helps!
