(pronounced play-jee-oh-sef-uh-lee)

Heard for the first time, the term “plagiocephaly” may sound like cause for alarm. The condition, sometimes known as “flat head syndrome,” affects nearly one in two infants today (47%), with experts recommending that one in every ten babies be evaluated for treatment. Plagiocephaly is characterized by the development of a flat spot on the back or side of the head. Many factors can cause flat spots. A baby’s skull is very soft and pressure from everyday surfaces, such as beds or car seats, can cause misshaping. Rest assured, it’s not your fault. The important thing is that you are doing something about it!


No. While plagiocephaly won’t have any lasting harmful effects on your baby’s neurological development, it is likely that, left untreated, the head will remain misshapen into adulthood.

When deciding whether or not to move forward with DOC Band® treatment, you might also consider your baby’s later years. Some issues that may arise are:

  • Noticeable facial asymmetry

  • Poorly fitting eyeglasses

  • Poorly fitting safety equipment, including sports helmets

  • Visible flat areas with short or cropped hairstyles

  • Jaw misalignment resulting in a crossbite or underbite

It’s our experience that parents of children diagnosed with plagiocephaly are often worried they’ve done something to cause it. Rest assured, plagiocephaly is quite common and many factors can contribute to the disorder—you’re not to blame. The important thing is that you are doing something about it!

Babies’ heads are soft and malleable and even gentle external forces, whether met in the womb or in baby’s daily routine, can cause misshaping. The good news is, babies with plagiocephaly typically respond very well to noninvasive treatments, such as repositioning techniques, which parents can practice at home, and the DOC Band, a custom cranial helmet that redirects baby’s natural growth into a normal head shape.

Babies can develop misshapen heads for a number of reasons:

Womb Position
Babies who become stuck in one position or do not have enough room to move in the womb are at risk of developing plagiocephaly. A breech orientation can also lead to an abnormal head shape.

Multiple Births
Plagiocephaly is common in cases of multiple births, where limited space can lead to distortion of the head.

Premature Birth
Premature babies have especially soft skulls, making them even more susceptible to misshaping. These babies often spend extended periods of time in the neonatal intensive care unit with the head in a fixed position while on a respirator. Premature babies are also more likely to be physically delayed, which can prevent normal movement of the head

Congenital Muscular Torticollis (CMT) is a condition in which the neck muscles are abnormally tight, causing baby’s head to tilt and/or turn to one side. Torticollis often causes the head to be held in a single position, which can lead to plagiocephaly. You can learn more about Torticollis here.

Carriers & Convenience Devices
While in car seats, bouncy seats and swings, baby’s soft head is often placed against a rigid, unyielding surface. Though normal use is not a concern, extended use—and allowing an infant to sleep in such devices, in particular—increases the risk of plagiocephaly.

The relationship between back-sleeping and plagiocephaly in infants is well-documented. While the American Academy of Pediatrics still recommends back-sleeping to prevent Sudden Infant Death Syndrome, they also recommend frequent rotation of baby’s head, as well as supervised tummy time. The recommended treatment for unresolved plagiocephaly is cranial helmet therapy


In the 1990s, the American Academy of Pediatrics (AAP) introduced the Back to Sleep campaign, which urged parents to put infants to sleep on their backs. While the AAP still recommends back-sleeping to prevent Sudden Infant Death Syndrome or SIDS (the Back to Sleep campaign has reduced SIDS-related deaths by more than half!), they have since recognized a correlation between back-sleeping and plagiocephaly.


Simple at-home practices, including supervised tummy time and repositioning techniques, are known to effectively prevent and improve abnormal head shapes. You can learn how to adopt these practices here.

Most insurance companies will require parents to practice repositioning techniques for at least two months before proceeding with a cranial orthotic such as the DOC Band. The DOC Band is the first FDA-cleared device of its kind and is proven to treat plagiocephaly in babies ages 3 to 18 months old. Each helmet is custom made to safely and effectively redirect the baby’s natural growth into a normal head shape. Learn more about the DOC Band here.
