The shape of a newborn's head may be affected by how the baby was positioned in the uterus, by the birth process, or by the baby's sleep position.
Positional plagiocephaly (say "play-jee-oh-SEF-uh-lee") means that a baby's head is flat in the back or on one side, usually from lying on the back or lying with the head to one side for long periods of time. Sometimes a baby's forehead, cheek, or ear may get pushed forward slightly on one side.
Babies can get a flattened head during the first few months of life. This is especially true since doctors began recommending putting babies down to sleep on their backs to reduce the risk of sudden infant death syndrome (SIDS).
Babies that are born early are more likely to get a flattened head. This is because their skulls are softer than in full-term babies.
Lots of time spent in a crib, in car seats, or in carriers or similar seats may lead to a flattened head. But you can do things to help keep your baby's head from getting flat, such as giving plenty of "cuddle time" by holding your baby upright.
Torticollis, or "wryneck," can also lead to a flattened head. It's a problem with your baby's neck muscles that causes the head to turn to one side. If your baby has torticollis, your doctor may recommend neck exercises to help your baby turn his or her head.
Doctors can diagnose positional plagiocephaly by looking at the shape of a baby's head. The doctor will check to make sure that your baby doesn't have a different condition that affects the shape of the head.
These tips can help prevent a flattened head:
If your baby has a flattened head, there are things you can do to help your baby's head become rounder. Encourage your baby to turn the rounded side of the head toward the mattress. Use the tips above, such as changing the crib location or the direction your baby lies in the crib. Other treatments may include exercises recommended by your doctor or a physical therapist. If you notice that your baby's head shape gets worse around 6 months of age, be sure to let your doctor know.
If the flattened head is severe or other treatments haven't worked, your doctor may recommend treatment such as a custom helmet. The helmet can help correct the shape of your baby's head. Surgery usually isn't recommended except in rare cases.
To help reduce the risk of SIDS, place your baby on his or her back to sleep. Even if your baby has a flattened head, don't stop placing your baby on his or her back to sleep. Just offer plenty of tummy time and cuddle time, and change your baby's head position.
Talk with your doctor about how to position your baby so that you don't increase your baby's risk of SIDS.
