How to Tell if Your Baby Needs a Helmet

Many parents notice flat spots or asymmetries in their baby’s head shape. Understanding these variations helps determine if medical intervention, like helmet therapy, is needed.

Recognizing Signs of Head Shape Irregularities

Parents can identify head shape issues by observing their baby’s head from various angles. Plagiocephaly is a common irregularity, characterized by flatness on one side of the back of the head. This causes asymmetry, often resembling a parallelogram when viewed from above. The ear on the flattened side may appear pushed forward, and the forehead or face on that side might seem more prominent.

Brachycephaly involves symmetrical flattening across the entire back of the head, resulting in a wider, shorter head with a vertical rise at the back. Scaphocephaly, less frequent, presents as a long, narrow head shape, often seen in premature infants. Observing the baby’s head from the top, back, and sides helps identify these patterns.

Common Causes of Head Shape Variations

Infant head shape variations primarily stem from continuous external pressure on soft skull bones. Positional factors are a frequent cause, such as prolonged time spent on their back (recommended for SIDS prevention), or in car seats, swings, and bouncers.

Intrauterine positioning can influence head shape before birth, especially in multiple pregnancies or when the baby’s head is constrained. Torticollis, a condition with tight neck muscles, can cause a baby to favor one side, leading to uneven pressure and a flat spot. Craniosynostosis, less common, is a serious condition where skull sutures fuse prematurely, causing abnormal head growth and requiring different treatment.

The Diagnostic Journey

Consulting a pediatrician is the first step for head shape concerns. The pediatrician will examine the baby’s head, assess neck movement, and evaluate developmental milestones. They may suggest conservative measures like repositioning techniques, more tummy time, and varying head position during sleep and play to alleviate pressure. If torticollis is suspected, physical therapy may be recommended to stretch and strengthen neck muscles, often improving head shape.

If conservative efforts don’t yield sufficient improvement or suggest a complex issue, the pediatrician might refer the baby to a specialist. These specialists, such as craniofacial surgeons, neurosurgeons, or orthotists, have expertise in managing head shape irregularities. Their assessment often involves detailed head measurements, and sometimes imaging studies like X-rays or CT scans to rule out craniosynostosis, which requires different treatment. The decision for helmet therapy is based on flattening severity, baby’s age, and progress with conservative management.

Understanding Helmet Therapy

Helmet therapy, or cranial remolding therapy, gently guides a baby’s head growth into a more symmetrical shape. The helmet applies gentle, consistent pressure to prominent skull areas, allowing flattened areas to grow and round out. This redirection is possible because a baby’s skull bones are soft and pliable, with spaces allowing for brain growth.

The process begins with an initial consultation where the baby’s head is measured, often using 3D scanning, to create a custom-fitted helmet. Babies typically wear the helmet for about 23 hours daily, removing it only for bathing and cleaning. Regular follow-up appointments monitor head growth and allow for adjustments. Treatment duration varies, commonly lasting three to six months, depending on severity and the baby’s age. Starting therapy before 9 months and consistent wear for over 15 hours daily can lead to better outcomes.
