Noticing a flat spot on your baby’s head can feel overwhelming. Many parents wonder whether their child needs a helmet, physical therapy, or simply more tummy time.
The answer depends on why the head shape changed in the first place.
At Back Bay Speech & Occupational Therapy, our pediatric physical therapists evaluate both movement and head shape to determine the most appropriate treatment plan.
What Causes Flat Head Syndrome?
Positional plagiocephaly develops when repeated pressure is placed on one part of a baby’s soft skull.
Common causes include:
- Torticollis
- Sleeping with the head turned one direction
- Limited tummy time
- Prematurity
- Multiple births
- Extended time in infant containers
Does Every Baby Need a Helmet?
No.
Many babies improve significantly with:
- Pediatric physical therapy
- Increased tummy time
- Position changes
- Stretching exercises
- Strengthening activities
- Parent education
Helmet therapy is generally considered when:
- Head shape remains significantly asymmetric.
- Conservative treatment has not been enough.
- The child is within the optimal age window.
- A specialist recommends cranial orthotic treatment.
What Does Pediatric Physical Therapy Do?
Physical therapy addresses the underlying reason many babies develop flat spots.
Treatment may include:
- Stretching tight neck muscles
- Strengthening weaker muscles
- Improving neck range of motion
- Encouraging symmetrical movement
- Improving rolling and tummy time tolerance
- Teaching positioning strategies
If torticollis is not treated, the flattening may continue because babies naturally keep resting on the same area.
Can PT Prevent Helmet Therapy?
In many cases, yes.
When started early, pediatric physical therapy often improves:
- Neck mobility
- Head positioning
- Symmetry
- Motor development
- Pressure distribution across the skull
Some babies will still benefit from helmet therapy depending on age and severity, but early PT may reduce the need or improve helmet outcomes.
What Happens During a PT Evaluation?
Your pediatric physical therapist will assess:
- Head shape
- Neck movement
- Muscle tightness
- Rolling
- Sitting
- Overall motor development
- Parent concerns
Together you’ll develop a home program that’s easy to fit into everyday routines.
Signs It’s Time for an Evaluation
Schedule an evaluation if your baby:
- Has a flat spot
- Always looks one direction
- Has a head tilt
- Hates tummy time
- Is delayed with rolling or sitting
- Uses one side more than the other
