stages sign and symptoms of Labour : we discuss here stage of labour. three stage are following.
First stage of Labour
First stage is from 0 to 10 cm dilatation of the cervix. The first stage of labour is divided in two phases.
Latent phase is from O to 4 cm dilatation of the cervix. It is a slow phase and the duration is 6—8 hours.
Active phase is from 4 cm till full dilatation of the cervix. During the active phase the
cervix dilates at rate of 1 cm / hour.
Second stage of Labour
Second stage is from full dilatation of the cervix to the delivery of the baby.
By definition the second stage is reached when the cervix is fully dilated. There is no
mention regarding the descent of the head. However if labour is progressing normally,
the head should be fully engaged when the second stage is reached. (No part of the head should be palpable per abdomen.)
The second stage is also divided into two phases
Passive phase: The foetal head will descend during this phase. the Mother must be discouraged from bearing down during descent phase of labour.
Active phase: After the descent phase when the foetal head reaches the pelvic floor mother feels the urge to bear down. She should be encouraged to bear down with contractions.

It begins after the baby is born and ends when the placenta separates from wall of uterus and is passed through vagina.
