Why Do My Neck and Shoulders Hurt From Feeding the Baby?

Hours a day, head down, shoulders up. A physiotherapist explains why feeding the baby makes your neck, shoulders and upper back ache — and the set-up changes that help.

Eight to twelve feeds a day. Twenty to forty minutes each. Head down, shoulders up, one arm holding a growing baby in the same spot over and over. If your neck, shoulders, or the space between your shoulder blades has been aching since the early weeks, it isn't because you're doing anything wrong. It's arithmetic: that's several hours a day in one position, with load, while you're sleep-deprived.

This post is part of our series on postpartum posture and pain. If your discomfort is lower down, start with why your back can still hurt months after having a baby.

Is neck and upper-back pain from feeding common?

Very. In a 2024 survey of almost 400 breastfeeding women published in BMC Musculoskeletal Disorders, pain in the neck, upper back and lower back was widely reported, and it varied with how long feeds lasted and which position was used. Other studies have reported similar findings, with seated positions often more uncomfortable than reclined ones. It applies to bottle-feeding too — the posture is often identical.

Why does feeding make my neck and shoulders hurt?

It's a load and position problem, not a damage problem. A few things stack up:

• Looking down for hours. Your head is heavy. Tip it forward to watch the latch or the bottle and the muscles at the back of your neck work much harder to hold it — for the length of every feed.
• Shoulders creeping up. Supporting the baby's weight with your arm, rather than with pillows or your lap, keeps the upper trapezius switched on. That's the muscle that feels like a tight rope from your neck to your shoulder.
• Rounding forward to meet the baby. Bringing yourself to the baby instead of the baby to you pulls the upper back into a C-shape and stretches the muscles between your shoulder blades. Stretched-and-working muscles ache.
• Always the same side. Many people favour one side for holding, burping, or the "good" breast. Asymmetry adds up.
• Everything around it. Carrying the car seat on one arm, rocking, and phone-scrolling during night feeds all use the same posture. Add broken sleep — which lowers pain tolerance — and it's a recipe for a sore neck.

Is it my posture, or is something wrong?

Most of the time, it's posture plus time plus load. That's reassuring, because posture isn't something to get "right" once; it's something to change often. The most useful posture is your next one.

That said, some symptoms aren't a posture problem. See a doctor or healthcare provider promptly if you have:

• Numbness, tingling, or weakness in your arm or hand that doesn't settle
• A severe or sudden headache, headache with visual changes, or a headache that's worse when you sit or stand up (especially after an epidural)
• Neck pain with fever, or a red, hot, painful area of the breast
• Pain after a fall or injury, or pain that is constant and wakes you regardless of position

What generally helps with neck and shoulder pain while feeding?

These are general first steps many people find helpful — educational starting points, not an individualized plan.

Set up before you sit down

1. Bring the baby up, not you down. Use pillows, a feeding pillow, or a folded blanket under the baby so they're at chest height and your arm rests rather than holds.
2. Support your back. Sit with your back fully supported against the chair or headboard, rather than perched forward.
3. Feet on something. A footstool or a stack of books raises your lap and reduces how much your arms have to do.
4. Try reclining. In the 2024 survey, neck pain was milder in women who fed lying down or semi-reclined. Laid-back or side-lying positions — where appropriate and safe for you and your baby — can take the neck almost completely out of the work.

During the feed

5. Look, then look away. Once the latch or bottle is settled, lift your gaze to the horizon. Glance down to check, then come back up.
6. Drop your shoulders and breathe. On a slow exhale, let your shoulders sink away from your ears. Many people find they were holding them up without noticing.
7. Switch sides on purpose. Alternate the arm you hold with, the side you burp on, and the hip you carry on.

Between feeds

8. Undo the position. A few times a day: gentle chin tucks (draw your chin straight back, as if making a double chin), slow shoulder rolls backward, and opening your arms wide against a doorway to stretch across the chest.
9. Strengthen the back of the body. The muscles between your shoulder blades often need strength, not just stretching. Gentle rows with a resistance band, or squeezing the shoulder blades back and down, are common starting points once comfortable.
10. Mind your breathing. Upper-chest, shoulder-lifting breathing keeps the neck muscles busy all day. Learning to breathe into the ribs and belly — the same diaphragmatic breathing that underpins core recovery — gives them a rest. If your ribs feel stuck or flared, this post on rib changes after pregnancy explains why.

How long does feeding-related neck pain last?

For many people it eases within a few weeks of changing set-up and adding some movement and strength — and it often improves naturally as feeds get shorter and babies get bigger and more independent. If it's still there after several weeks of consistent changes, or it's getting worse, it's worth seeing a licensed physiotherapist in your area for an individualized assessment.

Why it matters beyond your neck

Your neck and upper back don't work in isolation. A rounded upper back changes how your ribs move, which changes how your diaphragm and deep core work together. That's one reason postpartum aches tend to travel — neck, then mid-back, then low back. Rebuilding the whole system, in order, is the idea behind rebuilding your core after a baby.

Cleared isn't the same as recovered — and a body that's feeding a baby for hours a day deserves a plan, not just a heat pack.
