there really is very little negative when it comes to a homebirth. If you have a skilled midwife with you then she will be equiped to deal with whatever this babe throws at her in most cases. You could find a student doula who is still completing their training - they need to attend births as part of their course and as such do not charge a fee for this. Maybe you should scare him with some of the ugliness that goes on in the hospital system - now that would be an eye opener for him.
