According to baby centre.co.UK You could try some natural techniques to speed your labour up:
If you're lying on the bed, get up! Being upright and mobile may strengthen your contractions, while also helping you to cope with them.
Take a walk to the toilet. A full bladder may slow down your labour by getting in the way of your baby's head descending.
Get into a warm bath or birth pool. This can reduce your need for an epidural or spinal pain relief.
If your baby is lying back-to-back, an experienced midwife may advise you to lie on your side, or try kneeling or standing lunge positions. This may help your baby to rotate to a better position for birth.
Have some private time with your partner. Turn the lights down low and have a cuddle, with some nipple stroking or breast massage. This may help your body to release oxytocin, the hormone that strengthens your contractions.
You could also try acupuncture or hypnosis during your labour.
