Labour is a regular & painful uterine contractions causing progressive dilation and effacement of the cervix. The World Health Organization defined normal birth as "spontaneous in onset, low-risk at the start of labour & remaining so throughout labour & delivery. The infant is born spontaneously between 37 and 40 completed weeks of pregnancy. After birth, mother and infant are in good condition."
Normal labour usually begins within 2 weeks of the estimated delivery date. In a first pregnancy, labour usually lasts 12 to 18 hours on average; subsequent labours are often shorter, averaging 6 to 8 hours.

A woman might have a plug of mucus and blood fall out of the opening to the cervix, sometimes called a "bloody show", in the third trimester, before labour starts. Sometimes, the amniotic sac might rupture, and is called "water breaking". Either of these can trigger the onset of labour and so-called true labour contractions. These pains are different from the milder, non-productive contractions you may experience earlier in pregnancy, known as Braxton Hicks contractions (or practice contractions). Once they start, true labour contractions progress in frequency, duration & intensity, and they can feel like waves that build up to a peak intensity and then gradually decrease.
However, false labour pains are not well-coordinated, do not progress, and are usually relieved with rest, analgesia, or sleep. They do not harm the baby.
Even though labour is a continuous process, we can see three stages of labour.
This first stage is again has two phases. The first phase is the early phase or latent phase and usually lasts up to 20 hours or until the cervix dilates to 3 centimetres. The contractions are irregular and of low intensity.
Then, regular contractions follow - they happen every 3-5 min and last about a min or more, and this causes the cervix to dilate from 3 cm to about 6 cm. This marks the beginning of the active phase of labour, during which the cervix dilates from 6 to 10 cm. Contractions are intense, each lasting between 60 to 90 seconds, with only 30 seconds to 2 min of rest in between. Sometimes, they even overlap a bit, with one contraction beginning before the previous one ends. Often, the amniotic sac also ruptures at this point if it hasn't already.
In this stage, the cervix will be fully dilated. It can be treated as the pushing stage. During this stage, the baby, and in particular the baby's head, has to pass through the maternal pelvis, and normal vaginal delivery takes place.
This stage starts with the delivery of the baby and ends with the delivery of the placenta. (The placenta is the organ inside the uterus that brings a baby nutrients and oxygen and carries away waste.) It usually takes 5 min to 30 min.
After your baby is born, the doctor will give the baby first to a paediatrician. If you and your baby are in good health, the doctor might wait a min or so before they clamp and cut the umbilical cord. This allows the baby to get some of the blood from the placenta. Then, the baby is shown to the mother, and skin-to-skin contact is established.
If there is an episiotomy (intended cut given at the vaginal opening), or any small tears, repair is done with suturing under local anaesthesia.
This stage begins with the delivery of the placenta and ends 1-2 hours later; it is meant for observation of vital signs of the mother, her bleeding and assessment of neonatal wellbeing. Breastfeeding is preferably initiated in this golden hour.
Initial examination — The goals of the initial evaluation are to:
The following assessments comprise the initial examination:
Oral intake - Hydration is necessary, and oral intake of water and fluids is encouraged during the latent phase of labour.
Intravenous fluids - We provide maintenance intravenous fluids whenever a patient is unable to tolerate or take oral fluids or is in the active phase of labour.
Regular medications – Patients can take their usual daily medications orally during the latent phase of labour; if absorption or oral intake is a concern, a non-oral route of administration is preferable.
Position - Patients should assume positions that are comfortable to them. The duration of the first stage is found to be shorter in patients in upright positions (standing, sitting, kneeling, walking around) than in those in recumbent positions or bed care. In complicated pregnancies, however, specific positions may be required for maternal or fetal monitoring.
Pain and pain management - The first stage of labour and the second stage of labour causes pain.
Continuous support - A nurturing, supportive companion during labour has obvious psychological benefits, and almost all pregnant people feel that frequent or continuous support during labour helps them cope with its challenges. It can be anyone- the partner, some close relative or a "doula". Continuous support can also improve obstetric outcomes.
Pain relief options - There are various pain management options. Ideally, patients can seek information about these prior to the onset of labour so they can make informed decisions about labour analgesia. Multiple nonpharmacologic, pharmacologic, and anaesthetic options (painless labour) are available to help manage pain. The choice depends on patient values and preferences unless the method has medical contraindications.
Induction of labour-In some cases, doctors will decide to "induce" labour. This sometimes involves first giving you medicine to soften your cervix. Medicine is usually needed to start contractions. This medicine is given by oral, vaginal route or into your vein (by "IV").
After birth, the paediatrician will do a quick examination to check your baby's body and general health. Part of this exam is known as "Apgar test." It checks baby's heart rate, breathing, movement, muscles & skin colour. Babies will get Apgar tests at 1 min and 5 min after birth.
Soon after birth, you can hold your baby and can even breastfeed them, if you choose to breastfeed. Your baby will then have a detailed check-up and receive a dose of Vitamin K soon after birth.
After you leave the hospital, you are counselled to call or visit the hospital emergency if you:
Every delivery and every experience are as unique as the mother and the baby themsleves. A brief knowledge about the journey helps you anticipate and plan things. Happy Birthing Moms!!!

The key criteria for normal labour are: spontaneous onset, near or full-term pregnancy between 37 and 42 weeks; the baby in a vertex position (head first), no complications, regular painful contractions causing dilation and cervical effacement, and spontaneous delivery with a healthy mother and baby.
"• The first stage is the early phase, which lasts up to 20 hours or until the cervix dilates to 3 cm. It is the active stage of labour. • The second stage is the pushing stage, where the cervix is fully dilated. • The third stage is the delivery of the placenta. After childbirth, the baby is handed to the paediatrician to check the baby’s health. • The fourth stage is for observing the mother’s wellbeing, her internal bleeding and initiating breastfeeding."
Labour experience is different for every woman. For some, it may last for a few hours, for others, it may test their emotional and physical limits. Typically, the average length of early labour varies from a few hours to a few days and is shorter for women with previous deliveries. Active labour lasts 4 to 8 or more hours, and on average, the cervix opens about 1 cm per hour. When it comes to pushing the baby, it may take longer for a woman who has had no babies before. The time to push the baby may be a few minutes to a few hours. Finally, the placenta is delivered in about 30 minutes. So the time for childbirth may be 12 to 24 hours for first-time moms and 8 to 10 hours for moms with previous pregnancies.
Yes. Natural birth may be painful. However, there are options to manage pain during a natural birth. An epidural is one such option that numbs the body from your waist down. There are various other pain management options, ranging from nonpharmacological, pharmacological and anaesthetic options. Consult your doctor to make informed decisions, as the choice depends on you unless there are medical complications.
