Understanding the Language of Delivery

Dilation

Dilation refers to the opening of the cervix, measured in centimeters from 0 to 10. When the cervix reaches 10 centimeters, it is considered fully dilated and ready for pushing.

Learn what cervical dilation means and how it is measured during labor

Effacement

Effacement describes how thin the cervix becomes as it prepares for birth, measured in percentages from 0% (not thinned) to 100% (fully thinned). Effacement and dilation often occur together, especially in first-time births.¹

Understand cervical effacement and how it relates to labor progress

Station

Station refers to how far the baby has descended into the pelvis, measured in negative and positive numbers. A station of 0 means the baby head is aligned with the ischial spines of the pelvis. Station helps providers understand how labor is progressing during the pushing phase.

Crowning

Crowning occurs when the baby head becomes visible at the vaginal opening, typically near the end of the second stage of labor. Many parents describe this as the moment when birth feels very real.

Learn what crowning feels like and what to expect at this stage of birth

Mucus Plug and Bloody Show

The mucus plug seals the cervix during pregnancy. When released, it may appear clear, pink, or blood-tinged. Losing the mucus plug can happen days or even weeks before labor begins.

Find out what losing the mucus plug means and whether labor is near

Perineal Massage

Perineal massage is a technique used late in pregnancy to gently stretch the perineal tissues. Some studies suggest it may reduce the likelihood of severe tearing in first births.²

Learn how to perform perineal massage and when to start

Episiotomy

An episiotomy is a surgical incision made in the perineum to enlarge the vaginal opening during birth. Routine episiotomy is no longer recommended³ and is typically reserved for specific medical situations.

Understand what an episiotomy involves and when it may be necessary

Breech Presentation

Breech presentation occurs when the baby is positioned feet- or buttocks-first instead of head-down. Position plays an important role in labor progression and delivery planning.

Learn about breech presentation and what options are available for delivery

Cephalopelvic Disproportion (CPD)

Cephalopelvic disproportion refers to a mismatch between the size of the baby head and the mother pelvis. True CPD is less common than once believed, but it can impact delivery decisions in certain cases.⁴

Understand what cephalopelvic disproportion means and how it affects delivery

Retained Placenta

A retained placenta occurs when the placenta is not delivered within a specified time after birth. Prompt treatment reduces the risk of bleeding complications.

Learn what a retained placenta is and how it is treated after birth

APGAR Score

The APGAR score is a quick assessment performed on a newborn at 1 and 5 minutes after birth to determine whether immediate support is needed.

It evaluates:

• Heart rate
• Breathing
• Muscle tone
• Reflex response
• Skin color

Find out what the APGAR score measures and what the results mean for your newborn

Patterned Breathing

Patterned breathing techniques are used during contractions to promote relaxation and focus. While methods vary, the goal is steady oxygen flow and emotional grounding.

Explore patterned breathing techniques and how to use them during labor

Why Understanding Birth Language Matters
