Share 'HELP--First time mom having a home birth & freaked OUT!'

Hello everybody,   I watched The Business of Being Born and decided a home birth is for me.  With that said, I need to know what I need to do to prepare myself for the birthing process, pain, etc?  Will I just know what to do?  What if there is complications as the baby is coming out?  Any and all info is much appreciated.   Thank you, Cheryl
