More than half of twins will be born vaginally.  The process of labour is the same as with one baby, but the babies will be very closely monitored.   This often means you are unable to use certain facilities available to other labouring mums, such as the birthing pool.  Also, because medical intervention may be required you will almost certainly not be able to deliver your babies in a birthing centre but will have to deliver on the main labour ward.  Some hospitals require that all twin mothers give birth in the operating room, even if they have a vaginal birth. You may be given a drip in case it is needed later and an epidural will often be recommended.  Once the first baby has been born, the midwife or doctor will check the position of the second by either feeling your abdomen and doing a vaginal examination or via an ultrasound.    If the second baby is in a good position to be born, the waters surrounding the baby will be broken and the second baby should be born very soon after the first because the cervix is already fully dilated.  If contractions stop after the first birth, hormones are usually added to the drip to restart them.  This means the second baby is usually born no more than 20 minutes after the first.  The second baby often changes position once the first is born.  If the second baby is breech your doctor may decide to allow the baby to deliver breech, to turn the baby externally or internally or even do something called a breech extraction (pulling baby out by the feet).
