Being told your baby is bottom-down at a routine appointment sounds like a problem that has already happened. Statistically it is usually a problem that is about to solve itself: 25% of babies are breech at 28 weeks or earlier, 7% at 32 weeks, and only 3% to 4% are still breech at term. Almost all of that difference is babies turning on their own, unprompted.
This guide covers what the odds actually look like week by week, the three types of breech and why the distinction matters, what external cephalic version involves and how often it works, what the evidence says about the exercises you will find online, and how the birth conversation goes if your baby stays put.
The short answer. A breech baby before 36 weeks is normal and usually temporary — most turn without help. From 36 weeks you will usually be offered an external cephalic version (ECV), where a doctor turns the baby by hand; it succeeds in roughly 58% to 60% of attempts and complications occur in only 1% to 2%. If ECV does not work or you decline it, the choice is between a planned caesarean and a planned vaginal breech birth, depending on the type of breech and what your unit can support.
The Odds, by Week
The single most useful thing to know is how fast this resolves on its own.
| Gestation | Babies in breech | What it means |
|---|---|---|
| 28 weeks or earlier | 25% | Expected. There is room to move and position changes daily. |
| 32 weeks | 7% | Most have already turned. Still no action needed. |
| Term (37+ weeks) | 3–4% | Now it is a decision, and you will be offered options. |
This is why nobody acts on a breech position found at the 20-week anomaly scan, and why a note in your record at 30 weeks is a description rather than a diagnosis. If you have been logging what each scan said, the trend is visible; our guide to the third trimester covers what else is being checked at these appointments.
The Three Types, and Why It Matters
- Frank breech — bottom down, legs straight up with the feet near the head. The most common, and the type most likely to be considered for a vaginal birth.
- Complete breech — the baby is sitting cross-legged, bottom down, knees bent.
- Footling or incomplete breech — one or both feet are below the bottom. This one is generally not considered suitable for a planned vaginal breech birth.
When you ask about birth options, the type is the first thing your obstetrician will name. It is worth knowing yours rather than just knowing "breech".
Why Some Babies Stay Breech
In most cases there is no findable reason, and nothing you did caused it. Recognised associations include prematurity, twins or more, too much or too little amniotic fluid, fibroids, an unusually shaped uterus, and a low-lying placenta.
One number worth knowing if this is not your first: having had a breech baby before raises the chance of another to around 10% in a second pregnancy and 27% in a third.
ECV: What Actually Happens
External cephalic version is usually offered from 36 weeks. A doctor uses firm, sustained pressure on your abdomen to turn the baby head-down, guided by ultrasound.
What the appointment involves
- A scan first, to confirm position, fluid and placenta
- Monitoring of the baby's heart rate before and after
- Usually a medication to relax the uterus
- Anti-D if you are rhesus negative
- The turn itself — a few minutes, sometimes two attempts
- Done where a caesarean could be performed, as a precaution
It succeeds in roughly 58% to 60% of attempts. It is more likely to work if you have given birth before, if there is plenty of fluid, and if the baby has not yet engaged in the pelvis. Complications are rare — about 1% to 2% of attempts — and the most common is a temporary change in the baby's heart rate, which is precisely what the monitoring is there to catch.
It is uncomfortable. Most women describe strong pressure rather than sharp pain, and it is over quickly. Slow, deliberate breathing genuinely helps here — the same techniques used for early labour work for a procedure that lasts five minutes.
After an ECV, call your maternity unit if you have any bleeding, abdominal pain that does not settle, contractions, fluid leaking, or if the baby's movements are reduced or different. This is standard advice after the procedure, not a sign anything has gone wrong.
What About the Exercises?
Forward-leaning inversions, spending time on all fours, moxibustion, swimming, ice on the top of the bump — the internet is full of methods, and it is easy to end up feeling responsible for a position you do not control.
Honest summary: the evidence that any of these turns a breech baby is weak. They are also, for the most part, harmless, and there is no reason not to spend time on hands and knees while you wait for 36 weeks. What they should not do is replace the conversation about ECV, or become one more thing to feel you failed at.
If Your Baby Stays Breech
Two real options, and the choice is a genuine one:
| Planned caesarean | Planned vaginal breech birth | |
|---|---|---|
| Usually offered when | Any breech type; the default in most units | Frank or complete breech, average-sized baby, flexed head, experienced clinician available |
| Generally not offered when | — | Footling breech, low-lying placenta, pre-eclampsia, unusual baby size or head position |
| Recovery | Abdominal surgery — see our recovery guide | As for any vaginal birth |
The deciding factor is often institutional rather than clinical: vaginal breech birth needs a clinician who does them regularly, and not every unit has one. Ask that question directly — "does this unit support planned vaginal breech birth, and who would attend?" — because the answer shapes everything else. It is also worth writing your preference into your birth plan, including what you want to happen if labour starts before a planned caesarean.
Call your maternity unit the same day if, at any point in a breech pregnancy, your waters break — see what to do when your waters break. With a breech baby the cord is more likely to slip down ahead of the presenting part, so this is assessed rather than watched at home. Call immediately, and if you feel something in the vagina, lie with your hips higher than your chest and call an ambulance.
At a Glance
A breech baby before 36 weeks is a description of today, not a prediction: a quarter of babies are breech at 28 weeks and only three or four in a hundred still are at term. From 36 weeks, ECV is the standard offer, works about six times out of ten, and carries a 1% to 2% complication rate. If your baby stays breech, the choice between a planned caesarean and a vaginal breech birth depends on the type of breech and on what your unit can actually staff. Ask which type yours is, and ask what your hospital offers.

Frequently Asked Questions
At what week should I worry about a breech baby?
Not before 36 weeks. At 28 weeks or earlier, 25% of babies are breech; by 32 weeks it is 7%; and only 3% to 4% are still breech at term. Most turn on their own, and a breech position at the 20-week anomaly scan means nothing at all about how your baby will be lying at birth.
What are the different types of breech?
Frank breech means the bottom is down with the legs straight up in front of the body. Complete breech means the baby is sitting cross-legged. Footling or incomplete breech means one or both feet are below the bottom. The type matters because it affects whether a vaginal breech birth can be offered.
What is ECV and does it hurt?
External cephalic version is when a doctor turns the baby head-down by pressing firmly on your abdomen, usually with a drug to relax the uterus and with the baby monitored throughout. It is uncomfortable and sometimes painful, but it takes only a few minutes, and complications are rare — around 1% to 2% of attempts.
How often does ECV work?
Roughly 58% to 60% of attempts succeed. Success is more likely if you have given birth before, if there is plenty of amniotic fluid and if the baby has not yet dropped into the pelvis. Some babies also turn back afterwards, though that is uncommon at term.
Can I turn my baby myself with exercises?
Positions such as the forward-leaning inversion and spending time on all fours are widely recommended and are unlikely to do harm, but the evidence that they turn a breech baby is weak. They are worth trying while you wait for 36 weeks; they are not a substitute for being offered ECV.
Can a breech baby be born vaginally?
Sometimes. It depends on the type of breech, the baby's size and head position, the placenta, your history and — crucially — whether your unit has clinicians experienced in vaginal breech birth. Footling breech is generally not considered suitable. Ask your obstetrician directly what your unit offers.
Why is my baby breech?
Usually there is no identifiable reason. Recognised associations include prematurity, twins, too much or too little amniotic fluid, fibroids, an unusually shaped uterus and a low-lying placenta. Having had a breech baby before also raises the odds — to around 10% in a second pregnancy and 27% in a third.
If my baby is breech, will I definitely need a caesarean?
No. The usual sequence is ECV offered at 36 weeks, and if that works you continue toward a normal vaginal birth. If it does not work or you decline it, you choose between a planned caesarean and a planned vaginal breech birth where one can be safely supported.
