Understanding Treatment Windows, Outcomes, and the Power of Early Intervention

Flat head syndrome, or positional plagiocephaly, is a common condition in infants that occurs when one part of the skull becomes flattened due to prolonged pressure. Many parents wonder when it’s “too late” to seek treatment and what options are available as their baby grows.

While it’s never too late to understand your baby’s head shape, there is a critical window when treatment is most effective. Timely assessment can make all the difference in what treatment options are available, and how successful they’ll be. In this blog, we explore head growth milestones, stages of correction, and why earlier intervention often leads to better results.

The first year of life is a period of rapid brain and skull growth. By the age of 12 months, a baby’s head reaches about 85% of its adult size. This growth slows significantly after the first year, which is why early treatment of flat head syndrome is often the most effective.

During this time, the skull bones are more malleable, and gentle redirection of growth through repositioning techniques (in mild cases) or cranial remodelling orthoses (like a ROKband) in more moderate to severe cases,  can produce significant changes in a relatively short time. Understanding this window of opportunity is key to making informed treatment decisions.

In the newborn stage, the focus is on prevention and observation. Tummy time, frequent holding, and adjusting sleep and play positions can help avoid uneven pressure on one part of the skull.

At this age, cranial remodelling is not recommended. However, if flattening is already noticeable, it’s best to connect with a pediatric physiotherapist, chiropractor, or osteopath etc., who can assess your baby’s head shape and support early intervention through repositioning and developmental strategies. Catching early signs helps monitor for progression and determine if further steps are needed.

This is the ideal window to assess and begin helmet therapy, if needed. Babies’ skulls are growing quickly, and repositioning alone may not be enough to resolve moderate to severe asymmetries.

With timely intervention, treatment durations tend to be shorter, and outcomes are often significant. ROKband treatment during this phase gently redirects new growth to the flattened areas, creating a more symmetrical head shape while the bones are still highly responsive.

Between 6 to 9 months, babies are still experiencing rapid head growth and their skulls remain highly responsive to cranial remodelling. Starting treatment in this window can still lead to excellent outcomes, though treatment durations may begin to extend slightly compared to babies who begin earlier. The earlier within this range treatment begins, the better the results tend to be.

As babies approach their first birthday, skull growth naturally begins to slow, but that doesn’t mean it stops. Cranial remodelling can still be effective, especially when the ROKband is worn consistently and monitored closely. While results may take more time, many families still see meaningful improvements during this stage.

After 12 months, the skull begins to harden, and growth slows considerably. That said, treatment may still be recommended in certain cases, especially if the asymmetry is severe and parents are highly motivated. Outcomes tend to be more subtle and treatment timelines are longer, but some correction may still be possible. A clinical assessment can help determine if a ROKband would be effective at this age.

Treatment is typically not offered beyond 18 months of age, as the skull bones have largely fused and head growth has significantly slowed. While cranial remodelling is likely no longer effective after this point, it’s important to remember that many children with residual flat spots go on to develop normally without any functional concerns. 

If families still have cosmetic questions or want further guidance, we recommend speaking with their trusted healthcare provider to explore long-term options.

Starting earlier offers:

• Shorter treatment times

• Increased treatment options

• Greater potential for visible change

• Reduced risk of long-term asymmetry

• Improved comfort and adaptability for your baby

Parents often say they’re glad they didn’t wait once they see the results. And for those unsure if treatment is needed, a free 3D head shape assessment can offer clarity and direction.

At ROKband, we use advanced 3D scanning technology to capture your baby’s head shape with precision and comfort. Our custom-designed cranial remodelling orthoses are lightweight, breathable, and designed to redirect growth gently and effectively.

With clinics across Canada and no referral needed, families can explore their options without pressure. Our experienced orthotists and clinicians guide you through every step of the process.
