The Stages of Labor, Explained
Key takeaways
- Labour has four real phases: the latent phase, the first stage (dilation to 10cm), the second stage (pushing and birth), and the third stage (delivering the placenta).
- For a first pregnancy, established labour to full dilation typically takes 8 to 18 hours; the pushing stage should generally last no more than 3 hours.
- The third stage — delivering the placenta — is usually over within 30 minutes to an hour, depending on whether it's actively or physiologically managed.
- Our own second stage (pushing) took about an hour, well within the typical range, even though the day leading up to it was much longer because of induction.
- The latent phase can take many hours or even days before labour is properly "established" — it isn't wasted time even when it doesn't feel like progress.
Before I understood labour as a set of named stages, I pictured it as one long, undifferentiated stretch of pain that eventually ended with a baby. It’s actually more structured than that, and knowing the shape of it in advance made our own very long day easier to make sense of while we were in it.
The latent phase: before it’s officially “labour”
The NHS describes the latent phase as the period when the cervix begins to soften and dilate, often with irregular contractions that can carry on for many hours, or even days, before labour is considered properly “established.” It’s easy to feel like nothing is happening during this stretch, especially if what you’re feeling turns out to be Braxton Hicks rather than real contractions — but even genuine early contractions that start and stop are groundwork, not a false start.
The first stage: established labour and dilation
Labour is considered “established” once the cervix has reached about 4cm dilation and contractions are regular and strengthening — this is also the point where it’s worth knowing the actual signs to watch for if labour is starting spontaneously rather than being induced. From there, the cervix needs to open to roughly 10cm before the next stage can begin. For a first pregnancy, this typically takes 8 to 18 hours from the start of established labour to full dilation, often somewhat faster — around 5 to 12 hours — in a second or third pregnancy. This is usually the longest single stretch of the whole process.
The second stage: pushing and birth
Once the cervix is fully dilated, the second stage begins: the pushing stage, ending with the baby’s birth. For a first baby, this stage should generally last no longer than about 3 hours; for people who’ve given birth before, it’s typically shorter, often within 2 hours. This is the stage most people picture when they imagine labour, even though — as the timeline above shows — it’s usually the shortest of the three main stages, not the longest.
The third stage: delivering the placenta
After the baby is born, the womb contracts to deliver the placenta. There are two ways this is managed: actively, with an injection that helps the womb contract (usually complete within about 30 minutes), or physiologically, letting it happen on its own without medication (which can take up to about an hour). Your midwife or doctor will talk you through which approach fits your situation.
How our own labour mapped onto these stages
Our own experience is a good illustration of why it’s worth separating “how long labour took overall” from “how long each actual stage took.” I’ve written the fuller account separately, but in short: from arriving at the hospital to our daughter’s birth was about 36 hours, because ours started with induction rather than spontaneous established labour — a long stretch of oral medication doses, then a drip, then a stall in dilation that nearly led to a C-section discussion. But once we reached full dilation, the second stage — the actual pushing — took about an hour, squarely within the typical range for a first baby. The overall length of our day was unusual for reasons specific to being induced; the pushing stage itself followed the same general pattern most first-time births do.
What I wish I’d known
I wish I’d understood beforehand that a long total labour and a long pushing stage are two completely different things, and that most of what makes an induced or complicated labour feel endless happens before the part everyone pictures when they say “labour.” Knowing that in advance would have made the waiting stretches feel less like something had gone wrong, and more like an expected, if uncomfortable, part of the actual process.
Frequently asked questions
How long does labour usually take for a first baby?
Established labour to full dilation typically takes 8 to 18 hours, with the pushing stage generally lasting no more than about 3 hours after that — though every labour varies, and induction can add considerable time before “established” labour even begins.
What’s the difference between the latent phase and the first stage?
The latent phase is the earlier, often irregular period of softening and slow dilation before labour is considered properly established. The first stage begins once the cervix reaches about 4cm and contractions are regular and intensifying.
Is the pushing stage really shorter than the earlier stages?
Usually, yes. Dilation from 4cm to fully dilated typically takes considerably longer than the pushing stage that follows it, even though pushing is the part most people associate with “labour.”
What happens during the third stage?
Your womb contracts to deliver the placenta, either with the help of an injection (usually complete within about 30 minutes) or naturally without medication (which can take up to about an hour).
Does induction change how these stages work?
It changes how you get to established labour — through medication rather than spontaneously — but once you’re in the first, second, and third stages, they generally follow the same pattern as a spontaneous labour would.
