The 5-minute reset a PT recommends for every new mom’s wrecked back–and how to protect yourself long term
When I had my first baby, I’d been practicing yoga for years. I had well-developed core strength, solid body awareness, and a level of flexibility that 20 years later, I can only dream about. My pregnancy was fairly easy. The physical demands of motherhood that came after? Holy smokes.
I spent countless hours nursing a baby who seemed to think my boobs were more Stretch Armstrong, less fully attached to my body. I hauled his ever-growing self around in a sling because he found the stroller to be an unacceptable mode of transport. There were endless torques and tweaks from lifting him in and out of car seats, swings, and playards. Even at 23, I felt like an elder who’d been dragged behind a horse. Another baby and 20 years later, I can still feel the imbalances in my body.
Turns out, we all feel like this. Talking to friends and colleagues about the topic, everyone had a story—from being prescribed muscle relaxers and starting physical therapy because of all the hunching to excruciating back pain that lasted years. The consensus: motherhood is more like a full-contact sport than anyone warns you about.
So I took my questions to Trudy Messer, PT, a member of the Relax the Back Wellness Council, to understand what’s actually happening to our bodies in that first year—and what, if anything, we can do about it.
The patterns nobody tells you about
The postural changes that occur in this first year of parenthood aren’t dramatic. They’re incremental, repetitive, and so universal they’re basically invisible. According to Messer, the two biggest culprits are forward head position with rounded shoulders—driven by the constant looking down during feeding, holding, and (let’s be honest) phone scrolling—and what she calls the “parent hunch,” the slouched sitting posture that becomes your default during every feed and every contact nap.
Over time, Messer explains, that forward head position contributes to neck pain, upper trap tightness, and tension headaches, while the hunch reduces spinal and rib mobility, which can affect breathing mechanics and shoulder function. None of this feels like an injury. It just feels like being tired. And that’s exactly why it flies under the radar.
“They don’t flip from ‘normal’ to ‘problem’ at a single moment,” Messer says. “It’s more like a drift across a threshold.” The warning signs? Persistent tightness that doesn’t reset with stretching, loss of the ability to comfortably sit upright without slouching, and a side dominance that becomes so extreme the opposite side feels weak or unstable.
What the one-hip carry is actually doing to your body
If you’ve ever caught your reflection while carrying a toddler and thought “what is happening to my posture,” Messer has the biomechanical answer, and it’s a whole body situation to untangle.
When you shift a baby onto one hip, your body creates a whole chain of compensations to keep you upright. The pelvis shifts to create a shelf for the baby. The torso leans the opposite direction to counterbalance. Your ribcage rotates toward the baby, making your breathing asymmetrical. The carrying-side shoulder hikes up while your hand and forearm grip constantly to stabilize. And the deep core system essentially checks out—stability gets achieved passively, through hanging on the hip joints rather than active muscle engagement.
Do this thousands of times on the same side—which, of course, you will—and you’re essentially locking in an asymmetrical system. The fix isn’t to stop carrying your kid (good luck), but to consciously alternate sides and use a structured carrier when you can, which distributes the load more evenly.
The cumulative cost of feeding posture
Nursing and bottle-feeding posture isn’t just a “bad position,” Messer points out—it’s a high-frequency, long-duration input into the body. When the cumulative effects go unchecked, she often sees chronic neck and upper back pain, shoulder impingement, headaches, fatigue with basic tasks, and wrist and thumb overload that can progress to chronic inflammation.
The goal isn’t to eliminate the posture (you still have to feed the baby), but to offset it consistently. Messer recommends better setup during feeding to reduce strain at the source—a properly positioned nursing pillow that brings the baby to you instead of you going down to the baby—along with frequent position changes and what she calls “movement snacks”: brief stretches to restore extension, rotation, and breathing throughout the day.
Floor-to-standing: the move you’re doing 30 times a day
Getting up off the floor while holding a baby is one of those deceptively simple tasks that exposes a lot of movement dysfunction, Messer says. Most of us default to an asymmetric, spine-dominant, get-up-any-way-possible pattern, which works in the moment but accumulates load through the low back, wrists, and shoulders over time.
A more sustainable version comes down to three principles: keep the load close to your body, break the movement into segments rather than powering through it, and use your legs as the engine instead of your spine. It’s not glamorous advice, but when you’re doing this move dozens of times a day, mechanics matter.
The stuff that flies under the radar
Pelvic floor recovery gets a lot of well-deserved attention postpartum, but Messer sees a category of “mystery pain” that actually originates from global movement changes—patterns that don’t feel pelvic-floor-related at all. Ribcage collapse that makes the upper back feel perpetually stuck. Loss of trunk rotation that forces compensatory movement through the low back, often showing up as SI joint irritation.
Sleep deprivation compounds all of it. It’s not just that you’re tired. Fatigue measurably changes motor control, pain sensitivity, and movement strategies. “The only time we heal is in deep sleep,” Messer says, “and many parents miss a lot of this in those first few months.” Stack that on top of the carrying and feeding patterns, and you have the recipe for the aches that new parents tend to accept as just part of the deal.
For C-section moms specifically, Messer notes that the bigger issue is often movement strategy adaptation rather than structural weakness. Many people unconsciously shift from dynamic pressure management—the diaphragm, deep core, and pelvic floor working together—to a protective global bracing pattern where everything is held rigidly. The goal in recovery isn’t to “turn the core back on harder,” she says, but to restore breath-led pressure management and layered activation.
If you have five minutes while the baby naps
When I asked Messer for the moves that address the most common first-year strain patterns, she was clear: five minutes isn’t a workout. It’s an interruption. And that’s the point.
90/90 breathing with reach: Lie on your back with feet on the couch or wall, hips and knees at roughly 90 degrees. Gently tuck the pelvis so the low back is neutral. Reach your arms toward the ceiling, inhale slowly through the nose, and on a long exhale, let the ribs soften down and in. This resets the system most affected by fatigue—breathing mechanics and pressure control—which are often disrupted by both feeding posture and sleep deprivation.
Supported thoracic extension: Sit on a chair or on the floor with a rolled towel or pillow behind the mid-back. Support your head if needed, gently lean back over the support, and let the ribs open without forcing the low back. This directly counteracts the flexed mid-back position that comes from hours of feeding and stroller pushing.
When to call in a professional
Messer says most postpartum patients can start with home strategies like posture changes, breathing work, gentle strengthening if symptoms are mild and improving over time. The threshold for seeking PT is when pain persists beyond a few weeks, starts to spread or affect multiple areas, or begins changing how you perform basic tasks like lifting and carrying.
“The key threshold is when the body is no longer naturally recovering and instead starts adapting around pain,” she says.
The real goal of year one
When I asked Messer what she wishes every new mom heard, her answer wasn’t about a specific exercise or stretch. It was a reframe.
In the first year postpartum, she says, most of what’s happening to your body isn’t about recovery from birth. Instead, it’s about how the repetitive daily tasks of caregiving gradually reshape your posture, breathing, and movement patterns. Discomfort often reflects coordination and load distribution issues, especially under fatigue, rather than true injury. The goal isn’t “bouncing back.” It’s maintaining enough movement options that your body doesn’t adapt too strongly to one set of positions.
Which is, honestly, the most useful thing anyone told me in 20 years of being someone’s mom. It’s not that parenthood broke my body. It’s that my body adapted to the demands—and kept adapting long after I stopped noticing. Knowing that earlier would have changed everything.
