Why Do Babies Get Tense?

By Lucy Bartlett (Nomad Chiropractic)

Please note all chiropractors listed on Bump & Bub Chiro have additional training in pregnancy, postpartum and paediatrics and are experts in their field.

We often think of babies as soft, flexible, and totally relaxed. But many newborns carry real tension in their bodies — sometimes from birth, sometimes from how they’re developing day to day. This tension can affect feeding, digestion, sleep, and even bonding — but it’s often subtle and misunderstood.

At Bump & Bub Chiro, our goal is to help you to find a chiro who’s not just going to “fix” tension but to understand where it’s coming from and gently help your baby let it go.

What causes tension in babies?

There are three main sources of stress or tension in an infant’s body:

1. Pregnancy Positioning

The womb is a beautiful container — but depending on space, baby size, or uterine tone, babies can develop tension from being compressed or stuck in one position. Examples include:

• Breech or transverse positioning

• Anterior placenta restricting head movement

• First twin “moulding” the second

• Baby stuck in one side of the pelvis (often left occiput transverse)

These patterns can cause cranial asymmetry, neck tightness, or body tension even before birth.

2. The Birth Process

Birth is the most physically demanding event a baby will experience — especially when:

• Labour is very long or very fast

• Forceps, vacuum, or C-section are used

• Baby’s head is engaged for a long time before delivery

• The shoulders or neck experience torsion or compression

• There’s cord pressure or meconium stress

These events can strain the cranial membranes, upper neck, or sacrum — and many babies express this as feeding issues, irritability, or a strong head preference.

Research shows that assisted births are more likely to result in mechanical tension patterns, feeding difficulties, and musculoskeletal asymmetries (Black et al., 2015; Røe et al., 2016).

3. Adapting to Life Outside the Womb

Even after birth, babies are constantly adjusting to gravity, feeding, digestion, and movement. Things that can build tension include:

• Long car seat use or being held in one position

• Reflux or digestive discomfort

• Repetitive head-turning preference (often linked to torticollis)

• Unintegrated reflexes causing startle, arching, or tight fists

Just like adults, babies store tension when they’re trying to adapt or compensate. The difference is — they can’t tell us in words.

How do I know if my baby is holding tension?

Signs of infant tension include:

• A head that always turns to one side

• Arching or stiffening when lying down

• Fussy during tummy time or difficulty lifting the head

• Clicking, chomping, or shallow latch

• A flat spot on one side of the head

• Fists that stay clenched, or arms that don’t relax

• Grunting, straining, or poor digestive rhythm

• “Over-alert” expression or very jumpy/startled behaviour

These are not problems to panic over — but they’re signs that the body might need support to relax, unwind, and rebalance.

What happens if tension isn’t addressed?

Unresolved tension can affect:

Feeding mechanics (leading to one-sided preference, swallowing air, fatigue)

Cranial development (plagiocephaly, torticollis)

Neurological regulation (irritability, colic-like crying, difficulty sleeping)

Motor milestones (rolling, tummy time, crawling)

Over time, babies may compensate — but that compensation can carry over into toddlerhood and beyond. Early support = fewer patterns to undo later.

One study found that babies with early musculoskeletal asymmetry were more likely to show delayed gross motor milestones and altered muscle tone at 6 months (Tudor et al., 2019).

How chiropractic care can help baby tension

At Bump & Bub Chiro, our chiro’s work with your baby’s nervous system, fascia, cranial bones, and tone to release patterns of tension. This might include:

• Gentle cranial holds to ease dural tightness

• Supporting primitive reflex integration

• Freeing up soft tissue restrictions around the neck, jaw, or sacrum

• Giving you tools for feeding, carrying, tummy time, and co-regulation

Often, what we see is that when a baby’s body relaxes, their whole experience shifts — feeding becomes easier, sleep deepens, and calm comes more naturally.

🌿 The Bump & Bub Chiro Difference

The chiropractors we reccommend don’t rush to adjust. We observe, listen, and respond to your baby’s signals. They explain what they see and invite you to be part of the process — because you’re the expert on your child.

Our care is always:

Baby-led and gentle

Rooted in nervous system understanding

Co-created with you as the parent

We also collaborate openly with lactation consultants, dentists, speech pathologists, GPs, and other providers to make sure your baby’s care is connected and holistic.

 

Important Considerations

Chiropractic care for infants is gentle, specific, and safe when delivered by a trained professional.
Techniques for babies are vastly different from adult adjustments, involving soft, sustained pressure similar to checking the ripeness of a tomato.
We work collaboratively with other healthcare providers, including paediatricians, IBCLCs, and maternal health nurses, to ensure your baby receives holistic and thorough care.

FAQ

  • Not always. Some parents bring their babies for wellness check-ups, while others seek care when concerns like tension, feeding, or sleep arise.

  • Chiropractic compliments—not replaces—medical and allied health care. Many families combine it with GP, paediatric, or lactation consultant support.

  • Chiropractors often focus on alignment, movement, and nervous system function, which may support babies as they reach important milestones.

  • Yes. Techniques are always modified to a baby’s size, age, and stage of development.

  • Adjustments for babies use fingertip pressure, gentle stretches, and subtle holds—completely different from adult techniques.
