Full dilation may occur in less than 1 hour,but in first-time pregnancies it can take up to 20 hours.The second stage extends from full dilation to birth.The third stage extends from birth to expulsion of the placenta and usually takes a few minutes.The fourth stage begins after expulsion of the placenta and lasts until homeostasis is re-established (about 2 hours).
