Labour has three stages: The first stage is when the neck of the womb (cervix) opens to 10cm dilated. The second stage is when the baby moves down through the vagina and is born. The third stage is when the placenta (afterbirth) is delivered.
Step by step explanation:
First stage: This starts with contractions and your cervix dilating and ends when your cervix is fully open.
Second stage: This is when you push your baby through the birth canal.
Third stage: This ends with the delivery of the placenta, also called afterbirth.
