You have your choice of homebirth midwives. CNMs are the only midwives that can also deliver in a hospital. No one can arrest you for having your baby at home. However, in some states a midwife can be arrested for attending your birth. It depends on where you live.
Some states are neutral and some states completely outlaw it.
Only your insurance company can answer that. It usually depends on whether it is legal or not and if you have to use a network provider. Your best bet is to call the company and ask. You may have to educate them on how much money they will be saving. All are online and can refer you to someone in your area teaching their classes.
