I loved getting in the pool during labour. The water brought the relief, buoyancy and privacy I needed at the time. You can hire a birthing pool from www.wondermum.co.nz
They also have some awesome natural pregnancy & labour support, as well as information and advice on common pregnancy complaints. Something like Rescue Remedy can help to calm your nerves and relax you. Remember the more relaxed you are the easier the birth
