Postpartum back pain affects more than two-thirds of women immediately after delivery, and for most, it resolves within six months. But “resolves on its own” doesn’t help when you’re trying to pick up your newborn and your lower back seizes up. The good news is that a combination of targeted exercises, smarter feeding positions, and simple daily adjustments can significantly reduce pain while your body heals.
Why Your Back Hurts After Delivery
During pregnancy, your body produces a hormone that loosens the ligaments around your pelvis, back, and abdomen to make room for the baby and prepare for delivery. That loosening doesn’t snap back the moment you give birth. Levels of this hormone drop after delivery but can take up to 12 months to return to normal, which means your joints and ligaments remain less stable than they were before pregnancy. This instability puts extra strain on your lower back with everyday movements.
On top of that, your deep core muscles, including the ones that wrap around your midsection like a corset, have been stretched for months. Many women also develop diastasis recti, a separation of the abdominal muscles along the midline. When these muscles can’t do their job of stabilizing your spine, your back muscles pick up the slack and fatigue quickly. Add in the constant bending, lifting, and hunching over a newborn, and it’s no surprise the pain flares.
Exercises That Target the Right Muscles
The most effective exercises for postpartum back pain focus on reactivating the deep stabilizing muscles of your core, pelvic floor, and lower back. A study of women with persistent back and pelvic pain after delivery found that all sixteen participants reported reduced pain and decreased disability after following an individually adapted exercise program targeting these muscles. The key is starting gently and building up.
Pelvic Tilts
Lie on your back with knees bent and feet flat on the floor. Gently flatten your lower back against the floor by tightening your abdominal muscles and tilting your pelvis upward. Hold for five seconds, then release. This is one of the safest starting exercises because it activates your deep core without putting pressure on a healing abdomen. Try 10 repetitions a few times a day.
Glute Bridges
From the same position as pelvic tilts, press through your heels to lift your hips off the floor until your body forms a straight line from shoulders to knees. Hold for a few seconds at the top, then lower slowly. Bridges strengthen your glutes and hamstrings, which directly support your lower back. If this feels easy after a few weeks, you can place a small ball or resistance band around your knees for added challenge.
Cat-Cow
On your hands and knees, alternate between arching your back upward (cat) and letting it dip toward the floor (cow). For new mothers, the focus should be on the mid-back and thoracic spine, which tends to get stiff from holding and feeding the baby. One important caveat: if you have diastasis recti, the cat-cow position can be painful and may worsen the separation. A standing modification works well instead. Simply stand with a slight bend in your knees and alternate between tucking and untucking your pelvis to get similar mobility without abdominal pressure.
Pelvic Floor Contractions
Your pelvic floor muscles work together with your deep abdominal and spinal muscles to stabilize your pelvis and lower back. Contracting these muscles (the same ones you’d use to stop the flow of urine) for five to ten seconds at a time helps rebuild that stability from the inside out. Aim for several sets throughout the day. If you’re unsure whether you’re activating the right muscles, a pelvic floor physical therapist can guide you with hands-on assessment or biofeedback tools.
Smarter Feeding Positions
Breastfeeding and bottle-feeding are some of the biggest contributors to upper and mid-back pain because they lock you into repetitive, hunched postures for hours each day. Research on breastfeeding ergonomics found that the position you choose makes a measurable difference in pain levels.
Women who nursed sitting in a chair or armchair reported significantly higher neck pain intensity than those who fed on a sofa or bed, or in a lying position. The core principle is that every part of your body should be supported during a feed. If you’re sitting up, use pillows to bring the baby to breast height rather than leaning down. A nursing pillow across your lap takes the weight off your arms and shoulders.
Lying on your side is one of the most back-friendly feeding positions, especially for longer sessions. Rest your head on a pillow or your forearm, and place a pillow between your knees and another behind your back to stabilize your pelvis. The laid-back or semi-reclined position also works well. Recline with a high pillow under your head and upper back so you don’t reflexively lift your head to watch the baby latch. Both positions take your spine out of the flexed posture that causes so much stiffness.
Daily Habits That Reduce Strain
Small adjustments throughout the day add up more than any single exercise session. When lifting your baby from a crib or bassinet, bend at the knees and hips rather than rounding your back. Lower the crib mattress rail before reaching in. When picking things up off the floor, squat or kneel rather than folding forward.
If you carry your baby in your arms for long stretches, switch sides regularly. Baby carriers that distribute weight across both shoulders and your hips are easier on your back than one-arm holds. When using a car seat carrier, hold it close to your body with both hands rather than carrying it at arm’s length on one side, which creates a significant asymmetric load on your spine.
Heat can help loosen tight muscles. A warm shower, heating pad, or warm towel on your lower back for 15 to 20 minutes offers temporary relief, especially before doing your exercises. Ice works better if you feel sharp or acute pain after a specific activity.
Safe Pain Relief While Breastfeeding
Acetaminophen and ibuprofen are both considered safe to use while breastfeeding, according to the Mayo Clinic. Ibuprofen has the added benefit of reducing inflammation, which can be particularly helpful if your pain is related to joint or ligament irritation. Topical treatments like menthol-based creams can also take the edge off localized soreness without significant systemic absorption.
When Pelvic Floor Therapy Helps
If your back pain persists beyond a few months or limits your ability to care for your baby, pelvic floor physical therapy is one of the most effective treatments available. A pelvic floor therapist assesses your core, pelvic floor, and spinal stability as a connected system rather than treating back pain in isolation. Treatment typically includes relearning how to activate deep stabilizing muscles, coordination and strength exercises (often using a stability ball), stretching, and ergonomic coaching specific to your daily routine with a newborn.
This approach works because the deep core, pelvic floor, and small spinal muscles function as a unit to stabilize your pelvis and lower back. When any part of that system isn’t firing properly, compensatory patterns develop that keep pain going. Individually tailored programs have shown meaningful reductions in both pain and disability for women with persistent postpartum back and pelvic pain.
How Long Recovery Takes
In a study of 817 women followed from pregnancy through at least 12 months postpartum, 67% experienced back pain right after delivery, but that number dropped to 37% by the follow-up exam. Most women who recovered became pain-free within six months. That timeline can be shortened with consistent exercise and attention to posture and ergonomics, but it’s worth knowing that some degree of discomfort in the first few months is extremely common and not a sign that something is wrong.
Your ligaments remain looser than normal for months after delivery, so returning to high-impact exercise or heavy lifting too early can set you back. Build intensity gradually, and treat the first six months as a rebuilding phase rather than a return to your pre-pregnancy routine.
Symptoms That Need Immediate Attention
Most postpartum back pain is muscular and positional, but certain symptoms signal a more serious problem. Numbness or tingling in your upper inner thighs, buttocks, or the backs of your legs, new difficulty controlling your bladder or bowels, progressive leg weakness, or sudden severe lower back pain that doesn’t improve with rest could indicate compression of the nerves at the base of your spine. This is a rare but serious condition that requires emergency evaluation. If you develop any combination of these symptoms, go to the emergency room rather than waiting for an office appointment.
