Educate yourself on the different positions that you can use during the pushing stage. Most doctors prefer that women deliver on their backs (for their convenience) and it reduces the pelvic outlet by 30%. Open your birth canal by getting off your back! If the exit is too small for baby, he or she might get stuck and this is when birth becomes a dangerous event! A doctor may overcompensate and pull or rotate your baby's head causing damage to the brachial plexus.
Watch this video then talk to your provider about using alternative positions. If you are planning on using an epidural during labor, simply roll over on your side to birth your baby.
