Helmet Therapy
Does My Baby Need a Helmet?
Understand positional plagiocephaly, when helmet therapy may be considered, and simple repositioning steps that can reduce flat spots before and alongside care.

Parents naturally worry when a flat spot begins to form on the back of a baby’s head. This is one of the more common concerns during early growth. Your pediatrician may first suggest positioning strategies to gently encourage a rounder shape. If those steps are not enough, helmet therapy may be discussed. When appropriately indicated and carefully followed, helmet therapy can help guide head shape. A more even head shape is mainly a structural/cosmetic concern for most positional cases, but early guidance still matters for families.
So—does my baby need a helmet? Expert evaluation is the reliable way to answer that question.
Parents benefit from clear information and regular checkups with their clinician. Simple daily habits can also reduce pressure on one area and may lessen the chance that a helmet will be needed. Supervised tummy time every day can reduce continuous pressure on the back of the head. Holding your baby in varied positions also helps distribute contact.
Many parents blame themselves when they hear a helmet may be needed. You may even wonder whether this frustrating flat-head concern—technically often called plagiocephaly—could have been avoided. The truth is that most babies do not have perfectly shaped heads. Most adults do not either. Small flat areas and mild unevenness are common. A larger flat area is often related to birth molding or to spending a lot of time on the back with the head turned the same way.
Your baby’s skull is soft, which means the bones can move more easily than in adulthood. That flexibility helps the head pass through the birth canal and allows brain growth in infancy. It also means that ongoing pressure on the back or side of the head can contribute to lasting shape differences if not addressed.

In positional plagiocephaly, head shape alone usually does not cause brain injury. So how do you know whether a helmet may be appropriate?
Your clinician checks head size and shape at well-baby visits, often every couple of months in infancy. If a flat spot has not improved by around 4 months, a cranial helmet may be considered. Helmet therapy is generally more responsive when started around 4–6 months of age, while growth remains active. After about 1 year, the skull becomes less malleable, so treatment is often less effective—though some later cases may still be individually assessed.
When correcting positional plagiocephaly with a helmet, the helmet is typically worn about 23 hours a day during treatment. Wear often continues for several months. Regular adjustments are needed as your child grows and head shape changes; these fittings and adjustments are done at CranioWell Orthotics & Prosthetics Centers.

Some research suggests that careful repositioning can help, especially in milder cases. Our tummy time guide may help. Your clinician may also recommend physical therapy for related issues such as torticollis (a tight or preferred neck turn).
These techniques can give flatter areas a chance to improve as your baby grows:
In many cases, head shape improves with time and activity as babies begin to move more. Helmet therapy can be a helpful option when flat spots are larger or persist despite repositioning. Ask your clinician whether your baby may benefit from a helmet and what you can do at home.

In short, paying attention to head shape is part of healthy early care. Clarifying whether a helmet is needed and starting appropriate steps early can help. If you suspect a helmet may be needed, speak with your clinician—and if helmet therapy is recommended, fitting is provided at CranioWell Orthotics & Prosthetics Centers.
