A quote from the RCM article that I referenced earlier:

"Use the 'all fours', hands and knees position – it is particularly effective, as it allows gravity to assist the birth without providing too much added impetus (as it would in the standing position). Many women with babies presenting in the breech choose this position spontaneously in labour. During the birth, this position will allow the baby's legs to flop forward, easing the emergence of the rest of her or his body."
