What back labour is

Some people feel labour almost entirely in their back. Not backache alongside contractions, but the contraction itself experienced as low back pain, often with little sensation in the front at all.

Tommy's records it as an ordinary variation: "For some people contractions may feel like extreme period pains. Others get backache instead of, or as well as, pain in the front of their bump."

The NHS lists backache among the five signs that labour may be starting, and describes it as "backache or a heavy, aching feeling". ACOG describes contraction pain as felt "in your back or pelvis".

What distinguishes it from ordinary pregnancy back pain is rhythm. Back labour comes in waves that build and fade with the contraction. It does not sit there constantly, and it usually gets worse over hours rather than staying level.

What a back-to-back baby is

Tommy's describes the two common head-down positions.

Anterior: "Most babies take a head-down position for birth, facing away from your tummy. This is called the anterior position. It's the ideal position for giving birth because it allows your baby to flex their back and neck with ease. Flexing their neck means that the narrowest part of your baby's head rests against your cervix, helping it to open during labour and birth."

Posterior: "If your baby is head down but facing your tummy, it is called the posterior position. Because their back is against your back, this position is often known as back-to-back."

And the link to pain, in Tommy's own words: "You may find that having a back-to-back baby causes back pain in late pregnancy and during labour."

How you find out

Tommy's: "Your midwife may be able to feel where your baby is during one of your antenatal appointments. They will do this by feeling your tummy (palpating) and checking where your baby's head and back is. Or you may have a scan in late pregnancy and find out your baby's position then."

NICE's intrapartum guideline includes abdominal palpation to determine "the baby's lie, presentation, position, engagement of the presenting part" in the initial assessment in labour, and a vaginal examination includes "the position of the presenting part". So the position is checked, and it is a reasonable thing to ask about.

It is also worth knowing that position changes. A baby who is posterior at an antenatal appointment may well have rotated by the time you are in established labour, and many do so during labour itself.

Can you turn a back-to-back baby?

This is the question the internet answers with enormous confidence and no evidence. Tommy's answers it honestly:

"Some midwives and antenatal teachers believe that spending time leaning forwards can help your baby to turn. You could get on your hands and knees, or lean forward over a birth ball. Although there is not much to suggest that this approach can help to turn your baby, these positions can make you feel more comfy during late pregnancy and labour, so could be worth a try."

Read that carefully. The recommendation is for comfort, not rotation. Spending your third trimester scrubbing floors on all fours because a website told you it would turn the baby is not supported by anything Tommy's or NICE publishes.

What is worth doing is the version with a reason attached: lean forward because it feels better, not because it will reposition anyone.

What actually helps the pain

The NHS gives one position-specific piece of advice: "If you've had lots of backache while in labour, kneeling on all fours may help."

Tommy's lists the movements and positions worth trying in labour, and several suit back pain particularly:

Kneeling on all fours.
Kneeling on the floor cradling a birth ball, or over the back of the bed.
Standing and leaning on a bed, table or your birth partner.
Rocking back and forth on, or gently bouncing on, a birth ball.
A lunge position with one knee bent, standing, kneeling or lying on your side — a peanut-shaped ball helps with this.

Tommy's notes that "some of these positions will make it easier for your birth partner to give you a massage or back rub", and the NHS advice for early labour includes having "your birth partner rub your back — this can help relieve pain".

NICE's pain advice for the latent phase covers the rest: "breathing exercises, having a shower or bath, and massage may reduce pain". The NHS adds that a warm bath helps and that "paracetamol is safe to take in labour".

Firm counter-pressure on the lower back — the heel of a hand or a fist pressed hard into the small of the back during a contraction — is what most birth partners end up doing. It is not in any guideline, and it is what people ask for.

What it means for how labour goes

Be careful with claims here. NICE does not publish outcome figures by fetal position for planned vaginal birth, so anyone quoting you a precise likelihood of a longer labour or an assisted birth is going beyond published guidance.

What NICE does say is that the baby's position is one of the things assessed when progress is slow: descent and rotation of the baby's head are part of the assessment for delay in the first stage, and part of the reassessment during active pushing. The NHS lists "if your baby is in an awkward position" among the reasons labour can be slower than expected.

So position is one factor among several, it is watched, and it frequently resolves itself as labour progresses.

What is worth letting go of

The idea that you caused it. Nothing you sat on, slept on or failed to do put your baby back-to-back.
Optimal fetal positioning as a project. Tommy's is clear that the evidence is thin. Comfort is a good enough reason to lean forward; it does not need a mechanism.
The assumption that back-to-back means a caesarean. Many posterior babies rotate in labour and are born vaginally.

When to call someone

Your midwife or maternity unit for guidance once contractions come every 5 minutes or more often, or are regular, strong and lasting at least 60 seconds — whether you are feeling them in your back or your front.
Urgently if your waters break, you have vaginal bleeding, your baby is moving less than usual, you are under 37 weeks and think you might be in labour, any contraction lasts longer than 2 minutes, or you are having 6 or more contractions every 10 minutes (NHS).
Your midwife or GP urgently if back pain in the second or third trimester comes with fever, bleeding or pain when you pee — that is a different problem from back labour.
Your local emergency number — 999 in the UK and Ireland, 911 in the US and Canada, 000 in Australia, 111 in New Zealand — if you lose feeling in your legs, bottom or genitals, or if you feel a strong urge to push and think the baby is coming.

The short version

Feeling labour in your back is a recognised variation, often linked to a baby lying back-to-back. Kneeling on all fours is the one position the NHS names for it, and firm counter-pressure is what most people end up asking for. Leaning forward is worth doing because it is more comfortable — Tommy's says plainly that there is little to suggest it turns anyone.
