List the three stages of childbirth. Approximately how long does each stage last?
What will be an ideal response?
Childbirth progresses in three stages. The first stage is labor and typically lasts 8 to 14 hours for a woman having her first child; for later-born children, the average is 3 to 8 hours. The second stage of childbirth is delivery, which can take from 30 minutes to an hour and a half. The third stage of childbirth occurs when the placenta separates from the uterine wall and is expelled by uterine contractions. This process can take up to half an hour.
