There is very little you are not guaranteed the right to have. Any and every hospital in the usa has a patient bill of rights, you are the boss. The boss of your body, your baby, your birth-IF you want to.
That is the kicker!
I encourage you to study your rights, your choices-over 100 of them will be made for you if that is ok. If it is not, pick up your patient rights from the hospital before birthing there. Read the paragraph about "you have the right to accept, refuse or deny any and all policies and procedures AND be respected for your choice".
Very few actually want the choices but if you do, the information is on the net, learn a few things to redirect staff nicely but clearly that you know who is birthing, even if they have forgotten-when pressed, staff WILL admit you have the right to make all decisions regarding your body, baby and birth.
