Your midwife will normally bring a homebirth kit to your home towards the end of your pregnancy, containing items which she might use. Ask her what is provided, and if there is anything else that she would like you to have ready. Some midwives suggest preparing a 'birth box' with items you'll need (see the list below).
“Remember this, for it is as true as true gets: Your body is not a lemon. You are not a machine. The Creator is not a careless mechanic. Human female bodies have the same potential to give birth well as aardvarks, lions, rhinoceri, elephants, moose, and water buffalo. Even if it has not been your habit throughout your life so far, I recommend that you learn to think positively about your body.” ― Ina May Gaskin
