There's a book called 'The Birth Partner' by Penny Simkin that might be useful to him, also an article on BB which is in the men's section but I really ought to update it, as I have stacks more tips now than when I wrote it!

It's great they leave you alone for the birth, it really is a natural process and not a medical event. It's a very scary thought though for most women to surrender and trust your body - we'd rather leave it to the 'experts' in this day and age but they don't always have your best interests at heart, rather their's - which could be a combination of anything really, convenience, litiation, comfort level (i.e. some wont like to be involved in a twin vaginal birth or breech etc as they have no real life skills in it - one of the joys of too much intervention, they lose their hands on normal birth skills).

WA has a great community midwifery program, every other state is at the complete envy of you guys over there!!! It's the easiest place to acheive a home waterbirth, which is fully (I believe) funded by the government.
