Prep the best u can
Instead of preparing to feel stressed by your new arrival; try to imagine the exciting possibilities of the this "new life" you will prepare to take part in the world.
I think "baby days" to be some of the most enjoyable of parenthood. A baby just wants needs to be taken care of--she is not going to ask for money, or the car, or roll her eyes at this point. Love your new baby. Welcome help. Relax.
