Hands and knees is also a gravity neutral position. It is a great position to help get a break from the intensity of contractions. It also works well for turning a posterior baby.
If your baby is posterior or you are experiencing back labor, this position can be comforting. It allows your doula or husband to massage your back or apply counter pressure to help you be more comfortable. You can also use this position to give birth.
