The video is an informative animated presentation of how the process of labour and delivery happens. During a vaginal child birth, the first stage of labour lasts for 12-19 hours and starts when the baby settles lower into the pelvis. In response, the cervix begins to efface or become thinner, and dilate or widen. During this time, the mother may feel strong, regular contractions occurring every 5-20 minutes, a lower back pain and cramping that doesn’t go away. At the beginning of stage 2 of labour, which usually lasts from 20 minutes to 2 hours, the cervix is fully dilated to 10 centimetres, and the baby’s head has moved beyond the cervical opening and into the birth canal. When the top of the baby's head appears or crowns, the doctor may make a small cut called the episiotomy, to enlarge the vaginal opening. The doctor will then give the mother advice and assistance in pushing the baby out.
