Supportive care provider. If you are unsure about anything, get a second opinion. If you are worried or are anxious about labor, it is worthy every penny to be reassured during labor by someone who believes birth is a natural function. One suggestion is to stay home under the observation of this person until labor is well established. This support person will be your advocate in the hospital to help you have the birth you want.
Some childbirth educators are willing to give labor support too.
Include what is important to you and that which you have discussed with your care provider. Give a copy to all labor attendants on hospital admission to be put on your chart. Know your hospital's VBAC policies and negotiate well before the birth for anything different. Try a variety of positions. Standing or walking instead of lying down facilitates labor and squatting to push can be most effective.
