Stress and worry will not help. The baby will need to be delivered whether you are scared or not so it's best to accept it as a natural part of your life. Women are having babies every minute and it's a natural physiological process. Remember the pelvis has ligaments which relax and allow the pelvis to increase by about 25%. Hence. large head will mostly be able to come thru. The cord around the neck as a single loop should not pose a problem. At times if baby is stuck and is unable to come thru the doctor may assist the baby using forceps or vaccum. You can read my articles on Babychakra on these types of birth. Keep positive. The best way to achieve something is by keeping your mental attitude positive.
