Although I prefer less regulation in principle, I believe it is important for expectant parents to be fully informed of both the risks and benefits, regardless of where the baby is born.  The critical element is that the risks/benefits be evidence based - published studies in reputable journals.

I would also add that as a father of four, none of whom were born at home, I do not feel that we received adequate disclosure of risks, especially as related to induction of birth and the increased risk of c-section.  Any regulation should include disclosure requirements for both hospital and home births.
