  • Labour follows clear stages: Terms like dilation (up to 10cm), effacement, contractions and transition describe how labour progresses and help your care team understand what your body is doing. 
  • Pain relief is flexible and individual: Options include gas and air, epidural, spinal block and movement-based comfort measures. You can use more than one, and plans can change as labour unfolds. 
  • Assisted delivery is common and safe: Around 1 in 8 UK births involve ventouse or forceps, used when labour isn’t progressing, you’re exhausted, or your baby needs help to be born safely. 
  • Birth doesn’t end when your baby arrives: The third stage of labour, delayed cord clamping and skin-to-skin contact support your baby’s transition and early bonding. 

Childbirth is jam-packed with jargon, and it doesn’t always come with explanations. 

Over the last 9 months, you've probably heard a lot of language that sounds familiar but is still shrouded in a little mystery. Not on our watch! We've put together this comprehensive guide to help you understand the terminology you might encounter during labour and birth. 

The basics: Labour and birth terms you'll definitely hear 

  • Augmentation: When labour has started naturally but needs support to keep progressing, often with synthetic oxytocin (Syntocinon). It's different from induction (which starts labour from scratch). 
  • Braxton Hicks: "Practice contractions" that can happen from the second trimester onwards. Unlike real labour contractions, these are irregular and don't cause the cervix to dilate. 
  • ContractionsThe rhythmic tightening and shortening of your uterine muscles during labour. They help your cervix to dilate and move your baby down the birth canal. 
  • Crowning: When baby's head reaches the vaginal opening and can be seen. This is an exciting moment during the second stage of labour when your baby is nearly here. 
  • Dilation: The opening and measurement of the cervix, measured in centimetres. Your cervix needs to dilate to 10cm (fully dilated) before you can start pushing. 
  • Effacement: The thinning and softening of the cervix as it prepares for labour. It often happens alongside dilation, especially in early labour. 
  • Epidural: A type of anaesthetic used to numb the lower half of the body. It's administered through an injection into your back and can provide effective pain relief during labour. 
  • Induction of labour: When labour is started medically, using methods such as a pessary, gel, breaking the waters or synthetic hormones. 
  • Show: Sticky pink mucus from your cervix that comes away just before labour starts or during early labour. It's a sign that your body is preparing for birth, though labour might not start immediately. 
  • Spinal block: A single injection of anaesthetic into the lower back, often used for caesarean birth or some assisted deliveries. It works quickly and wears off faster than an epidural. 
  • Transition: The final phase of the first stage of labour, usually when you're dilated between 7-10cm. This is often the most intense part of labour. 
  • Waters breaking: When the amniotic sac (the fluid-filled membrane surrounding your baby) ruptures. You might experience a gush of fluid or a slow trickle. Labour often begins after your waters break, though it can happen the other way around. 

Medical professionals you'll meet

  • Anaesthetist: A doctor who specialises in providing pain relief, including epidurals and spinal blocks. Don't hesitate to ask for extra pain relief. Your healthcare team can advise on safe options, including paracetamol and ibuprofen. 
  • Midwife: A healthcare professional who specialises in caring for women during pregnancy, labour, and the postnatal period. 
  • Obstetrician: A doctor who specialises in pregnancy and childbirth, particularly when complications arise. 
  • Paediatrician: A doctor who specialises in the care of newborn babies and children. They may be present at the birth if your baby needs extra support. 

Assisted delivery 

Sometimes babies need a little extra help to be born safely. Around 1 in 8 births in the UK involve assisted delivery.  

Your healthcare team might suggest assisted delivery if: 

  • Your baby is showing signs of distress or there are concerns about their heart rate 
  • Your labour isn't progressing as expected 
  • You're unable to push, or have been advised not to push due to a health condition (such as very high blood pressure) 
  • You're exhausted after a long labour 
  • Your baby is in a position that makes birth more difficult 

Episiotomy 

An episiotomy is a deliberate diagonal cut made in the perineum (the area between your vagina and anus) to make the vaginal opening wider. This is often needed during assisted delivery to help your baby be born more easily and to reduce the chance of uncontrolled tearing. 

You'll be given a local anaesthetic injection to numb the area unless you already have an epidural in place. After birth, the cut will be repaired with dissolvable stitches. Episiotomies aren't done routinely – they'll only be suggested if necessary, and you'll be asked for your consent. 

Forceps 

Forceps are smooth, curved metal instruments designed to carefully fit around your baby's head. They look a bit like large spoons or tongs. Your doctor will place the forceps around your baby's head, wait for a contraction, and ask you to push while they gently pull. 

Some types of forceps are specifically designed to help turn your baby if they're in an awkward position, such as facing upwards (occipito-posterior) or to one side (occipito-lateral). 

Forceps may leave temporary marks on your baby's face, but these usually disappear within 24-48 hours. 

Ventouse (Vacuum Extraction) 

A ventouse is a suction cup (made of plastic or metal) that attaches to your baby's head to help guide them through the birth canal. Your healthcare professional will wait for a contraction, then ask you to push while they gently pull. This may take several contractions. 

Other important terms

  • Active birth: Using movement, upright positions, and breathing techniques during labour, rather than lying on your back. 
  • Breech: When your baby is positioned bottom-first or feet-first instead of head-down. 
  • Catheter: A thin tube inserted into your bladder to drain urine. You might need this during an epidural, after assisted delivery, or if you're having difficulty passing urine. 
  • Cephalic: When your baby is positioned head-down, ready for birth. 
  • CTG (Cardiotocography): A type of monitoring that tracks your baby’s heart rate and your contractions during labour. 
  • Engaged: When your baby's head has moved down into your pelvis, ready for birth. You might hear your midwife say "the head is engaged." 
  • Meconium: Your baby's first poo, which they sometimes pass before or during labour. If meconium is present in the amniotic fluid, it can stain it green or brown, and your healthcare team will monitor your baby more closely. 
  • Occipito-posterior (OP): When your baby is head-down but facing your tummy rather than your back. Labour can be longer, but many babies turn during birth. 
  • Oxytocin: A hormone your body produces during labour that stimulates contractions. It can also be given artificially (often called Syntocinon) to help get labour started or keep it progressing. 
  • Perineum: The area of skin and muscle between your vagina and back passage (anus). Whether you've had an episiotomy or a tear, keeping this area clean and dry is essential to prevent infection. Your stitches are usually dissolvable and should heal within 4-6 weeks. 
  • Station: A way of describing how far down into the pelvis your baby’s head has moved. It helps your midwife or doctor assess progress during labour. 

Caesarean birth: Common terms you may hear 

  • Caesarean section (C-section): A surgical birth where your baby is delivered through an incision in your abdomen and uterus. A C-section may be planned in advance or recommended during labour if it’s the safest option for you or your baby. 
  • Drape: A sterile screen placed across your chest during surgery. Some parents choose a lowered or clear drape so they can see their baby being born. 
  • Emergency C-section: A caesarean that’s needed quickly during labour due to concerns about your or your baby’s wellbeing. While urgent, it’s carefully managed by an experienced team. 
  • Gentle/Family-centred C-section: An approach that supports skin-to-skin contact, delayed cord clamping and a calmer birth environment, where clinically appropriate.  
  • Planned (Elective) C-section: A caesarean that’s scheduled ahead of time, often due to your baby’s position, a previous birth, or a medical condition. 
  • Spinal anaesthetic: A fast-acting form of pain relief commonly used for C-sections. It numbs the lower half of your body while allowing you to stay awake for your baby’s birth. 

After birth: The final stage 

  • Third stage of labour: The period between your baby being born and the delivery of the placenta. 
  • Placenta (Afterbirth): The organ that supported your baby during pregnancy. It’s delivered shortly after your baby is born. There are 2 ways to manage this stage of labour: 
  • Active: When you have treatment to make it happen faster 
  • Physiological: When you have no treatment and this stage happens naturally 
  • Delayed cord clamping: Waiting at least 1 minute (or until the cord stops pulsating) before clamping the umbilical cord, allowing extra blood to pass to your baby. This supports your baby's iron stores and helps with the transition to breathing. 
  • Skin-to-skin contact: Placing your baby directly on your chest after birth to support bonding, warmth and early feeding. 

Final thoughts 

This guide covers the most common terms you'll encounter, but don't hesitate to ask your midwife or doctor to explain anything you don't understand. No question is too small, your healthcare team wants you to feel informed and supported throughout your birthing journey. 

Remember, every birth is unique, and what matters most is that you and your baby receive the care you need for a safe delivery.
