I guess everyone else has already addressed the safety issues so I just wanted to say something about the "squeamish factor"

Trust me. Your DP is going to see a heck of a lot less blood and gore in a homebirth than he will see in hospital.

Hospitals like to have bright lights on so they can see what they are doing for one thing...which means you get to see everything in technicolour. Homebirths are usually low light affairs

Secondly, the things that cause lots of body fluids, blood etc to occur during birth are breaking waters, IV's, syntocinon, episiotomies (oh this is a BIG one on the blood factor) and, if you're unlucky and lose the hospital lotto - caesareans.

ALL of these things are rare or non existent in homebirth and relatively common in hospital birth. And obviously caesareans don't happen at home
