Back pain while breastfeeding is one of the most common complaints in the postpartum period — and one of the least talked about. You are recovering from pregnancy and birth, feeding your baby around the clock, and doing it all in positions you would never normally hold for this long. Something has to give.
The good news is that breastfeeding back pain is rarely something you have to simply endure. In most cases, it responds well to small adjustments: how you sit, how you hold your baby, and how you support the muscles pregnancy has altered. This article walks through why the pain happens, where it tends to show up, and what actually helps.
Is back pain normal while breastfeeding?
Back pain during breastfeeding is extremely common, particularly in the first few weeks when feeding sessions are long and frequent. Your body is still recovering, your hormones are still shifting, and you are spending several hours a day in positions that place real strain on the spine.
Some degree of discomfort during this period is normal. That said, there is a difference between a sore back from breastfeeding that responds to rest and better positioning, and pain that needs medical attention.
Speak to your GP or midwife if you experience any of the following:
- Sharp or shooting pain in your spine or down one leg
- Numbness or tingling in your arms, hands, or fingers
- Pain that does not improve with rest or position changes
- Pain that began suddenly after a fall or injury
For most mothers, what they feel is a dull ache in the upper or lower back, tension across the neck and shoulders, or general muscle fatigue. These are signs your body is under strain — and strain can be reduced.
What causes breastfeeding back pain?
Breastfeeding back pain rarely has a single cause. It tends to build up from several factors happening at the same time.
Poor posture during feeding
The most immediate culprit. Most mothers lean forward towards their baby rather than bringing the baby to their breast. This rounds the upper back, drops the shoulders forward, and places significant strain on the muscles along the spine. Repeated over days and weeks, those muscles stay contracted — producing tightness across the shoulders and an aching mid or lower back.
Lack of proper support
Breastfeeding back ache is often made worse by feeding without physical support. Sitting on a surface that is too soft, or in a chair where your feet do not reach the floor, forces your back muscles to compensate for the instability. Arms held unsupported while carrying the baby add considerable weight — and that strain travels straight up into the shoulders and neck.
Muscle weakness after pregnancy
During pregnancy, the deep abdominal muscles stretch significantly and the pelvic floor is placed under sustained pressure. After birth, these structures do not automatically return to full function. When this deep stabilising system is weakened, the back compensates — which is why the pain can feel disproportionate to what you are actually doing.
Hormonal changes
The hormone relaxin, produced during pregnancy and while breastfeeding, loosens ligaments and joints. With looser ligaments comes reduced joint stability, meaning positions and loads your body would have managed easily before pregnancy can now cause discomfort. This is a temporary state, but it means your joints need more support during this period.
Long or frequent feeding sessions
Holding any position for an extended period leads to muscle fatigue. Static positions reduce circulation to the muscles involved, so tension builds and recovery slows. This is not a reason to cut feeds short — but it is a reason to be intentional about how you sit, and to move between feeds whenever you can.
Common areas of discomfort
Breastfeeding back pain does not always feel the same from one mother to the next. Where it shows up tends to depend on your feeding position, the age of your baby, and how your body has been coping since the birth. Two areas come up most consistently.
Upper back and neck pain from breastfeeding is extremely common in the first weeks. It develops when you spend long stretches looking down at your baby — checking the latch, adjusting position. The head is heavy, and tilting it forward places a significant load on the cervical spine and the muscles across the top of the back.
Lower back pain tends to come from sitting without adequate lumbar support — on a soft mattress, a low sofa, or a chair that offers nothing to the curve of the spine. Combined with postpartum core weakness, this can become persistent. Both areas frequently appear together, especially during night feeds when you are tired and less likely to be mindful of your posture.
How to relieve breastfeeding back pain
The golden rule: bring the baby to you
Instead of leaning in towards your baby, bring your baby up to your breast. Use pillows or a nursing cushion to lift them to the right height rather than bending your back and neck down to meet them. When your baby is properly supported, you can sit back, keep your spine upright, and relax your shoulders. The latch often improves too.
Use a nursing pillow
A firm nursing pillow placed across your lap raises your baby to breast height without you having to hold all of their weight through your arms and shoulders. Add a pillow behind your lower back if you are on the sofa — it makes a significant difference to how long you can sit comfortably.
Heat and cold therapy
For a sore back from breastfeeding, heat is usually the more effective option. A warm heat pad applied to the tense area for 15 to 20 minutes helps relax muscle fibres. Many mothers find it useful before a feed, so the muscles are less contracted when they sit down. Cold therapy — an ice pack wrapped in a cloth — is better suited to acute or inflamed pain in the lower back.
Gentle stretching
Moving between feeds helps release the tension that builds during static positions. Three stretches that are safe for the postpartum period:
- Cat-Cow: on all fours, arch your back upward on the exhale, then let it drop and lift your head on the inhale. Repeat 8 to 10 times. Gently mobilises the entire spine.
- Child's Pose: from all fours, sit your hips back towards your heels and extend your arms forward. Hold for 30 to 60 seconds. Releases the lower back and hips.
- Shoulder Rolls: roll both shoulders backwards in slow circles — 10 times backwards, then 10 forwards. Effective for upper trapezius tension caused by hunching during feeds.
💡 If you are unsure whether these exercises are appropriate for your stage of recovery, a women's health physiotherapist can advise on where to start.
The best positions to prevent breastfeeding back pain
Side-lying position (best for resting)
Lie on your side with your baby facing you at the same level. There is no weight to support and no posture to maintain — almost all strain is removed from the back. This position is particularly useful during night feeds or when you are exhausted. It is also one of the most recommended positions for breastfeeding after a c-section: with no pressure on the abdominal wound and no need to sit upright, it allows you to feed comfortably while your body heals. A pillow between your knees supports the hips and lower back.
Laid-back position (biological nurturing)
Recline at roughly 45 degrees and let your baby lie face-down on your chest. Gravity reduces the effort required to hold the baby, and many newborns latch more deeply in this position. It works well during daytime feeds when you can settle into a reclining chair or a well-propped sofa. Make sure your head and neck are supported to prevent upper back tension.
Supported upright position
When sitting upright, your feet should be flat on the floor (use a footstool if needed), your lower back in contact with the chair back or a lumbar cushion, and your baby raised to breast height with a pillow. Avoid perching on the edge of the seat. The further back you sit, the more the chair takes the load. Armrests at the right height reduce strain on the shoulders and neck considerably.
Exercises to reduce and prevent back pain
Stretching brings relief, but if you want to address breastfeeding back pain at its root, targeted exercise is where lasting change happens. The goal is to rebuild the foundations pregnancy has altered — not to push hard. Start gently, listen to your body, and progress gradually.
Core and pelvic floor recovery
This is the area that makes the biggest long-term difference. When the core and pelvic floor are weakened after birth, the back compensates — and that compensation is often where the pain originates.
Diaphragmatic breathing is the starting point. Lie on your back with knees bent. Breathe in slowly into your ribcage and abdomen through your nose, allowing your belly and sides to gently expand. As you inhale, the diaphragm descends and the pelvic floor naturally lengthens and relaxes. On the exhale, allow the ribs and abdomen to soften back inward naturally without forcefully gripping the core. This helps restore pressure management, breathing mechanics, and deep core coordination without placing strain on the back or pelvic floor.
Once you are comfortable with breathing coordination, gentle core and pelvic floor activation can be added by gently engaging the lower abdominal wall and pelvic floor on the exhale. This should not be forceful, just a gentle squeeze or brace. Kegel exercises work directly on the pelvic floor muscles most affected by pregnancy. A gentle contraction — lifting and holding for 3 to 5 seconds, then fully releasing — repeated 10 times, twice a day, is an effective starting routine. The release matters as much as the contraction, particularly for women experiencing pelvic tension, pain, or difficulty relaxing muscles.
💡 If you find it difficult to feel these muscles or to know whether you are contracting correctly, a Kegel trainer such as the Perifit uses biofeedback to show you in real time whether the exercise is working. For mothers dealing with back pain after breastfeeding, knowing the pelvic floor is actually activating — rather than hoping it is — can improve awareness and help guide recovery.
Upper back strengthening
Once the core is beginning to recover, gentle upper back work helps correct the muscular imbalance created by months of forward-rounded posture.
- Wall angels: stand with your back flat against a wall, arms raised to the side at shoulder height with elbows bent at 90 degrees. Slowly slide your arms upward along the wall and back down. Keep your lower back in contact with the wall. 2 sets of 10.
- Resistance band rows: anchor a light band at chest height. Pull both hands towards the side of your ribs while squeezing your shoulder blades and elbows together. Hold for 2 seconds, release slowly. 2 sets of 12, two to three times a week.
- Superman holds: lie face down, arms extended in front. Lift your right arm and left leg a few centimetres off the floor, hold for 3 seconds, and lower. Alternate sides for 10 repetitions each. This is a progression for later in postpartum recovery when cleared for progressive strengthening and when symptoms such as pain, heaviness, or abdominal doming are absent.
Breastfeeding back pain is common, but it is not something you have to accept as inevitable. In most cases, the combination of a few simple adjustments — how you position yourself and your baby, how you support your body during feeds, and how consistently you work on core and pelvic floor recovery — makes a significant difference within a few weeks.
Small changes compound. Getting your feeding position right protects your back in every single session. Building back your core and pelvic floor gives your spine the support it relies on. Moving gently between feeds prevents the muscle fatigue that comes from staying still for too long.
If the pain persists despite these adjustments, or if you have any concerns about your recovery, speak to your midwife, GP, or a women's health physiotherapist. You do not have to manage this alone.
