If your baby has entered the pelvis facing your abdomen instead of your back, this is known as a posterior position. This may mean you have a longer labour and you may experience more back pain than if your baby were facing towards your back. For most women, your baby will turn around during labour, however some will not. You may be able to push your baby out without any assistance, however some women will require assistance from your doctor to help turn your baby’s head and/or help it out with forceps or vacuum.
