How to Prevent Flat Head in Car Seat
By Caitlin Lipscomb, PT, DPT
When you have a new baby, there are thousands of concerns constantly running through your head. Is he getting enough to eat? Is her crib safe? Is that poop a normal color? And in recent years, a new concern is plaguing parents -- is my baby's head getting flat? Plagiocephaly, or "Flat Head Syndrome", is a common and treatable condition seen in many infants, but it can be alarming when first spotted by parents. Read on to learn more about plagiocephaly and how to prevent it from developing in your infant.
What is Plagiocephaly (aka "Flat Head Syndrome")?
Since the 1990's, the American Academy of Pediatrics (AAP) has promoted the "Back to Sleep" campaign, which recommends that infants should only sleep on their backs. Although this has helped reduce the incidence of sudden infant death syndrome (SIDS), head and neck issues like plagiocephaly have increased. Plagiocephaly is the flattening that is seen on the back of a baby's head, often on one side, as a result of prolonged pressure. In more severe cases of plagiocephaly, additional deformity of the skull can be seen such as bumping out of the forehead or asymmetrical alignment of the ears.
How Does Plagiocephaly Occur?
A flat spot on a baby's head can develop in a few different ways. Flattening can happen in the womb if the head is positioned against the pelvis for an extended period or if there is less space for the baby to easily change positions, such as in the case of twins or triplets. A baby can also appear to have a misshapen head following delivery, but this will generally only last a few days.
More commonly, plagiocephaly develops after birth when the baby is spending a significant amount of time on his or her back. A newborn often spends anywhere from 14-18 hours a day sleeping, and if a parent is following the AAP's guidelines, that means lying on their back in a crib or bassinet. And if a baby is spending a significant amount of time in a car seat, swing, or bouncy seat, almost the entirety of their day could be spent on their backs! Furthermore, a baby's skull is designed to be soft and moldable to allow for rapid growth in the first few months of life. This "soft head" combined with countless hours lying on their backs is the perfect recipe for the development of plagiocephaly.
How Do You Spot Plagiocephaly?
Even for those who have never heard of plagiocephaly, the first signs of it developing can easily be spotted by parents. You may notice the following:
● The center of the head looks flat or less rounded than it once did
● One side of the back of the head looks flatter than the other side
● Your baby has a bald spot on one part of their head
● Your baby strongly prefers keeping their head turned in one direction (to the right or to the left) whenever they are lying on their backs
● One ear looks flattened or like it is pushed further forward than the other ear
● One side of the forehead looks like it is bulging out further than the other side
● Asymmetry of your baby's eyes, cheeks, or jaw (in severe cases)
How Do You Prevent Plagiocephaly?
Although it might seem like the development of a flat spot is inevitable in the newborn phase, you can use the following tips and positioning strategies to prevent plagiocephaly (and promote appropriate development) in your baby:
● Tummy Time: By practicing 30-60 minutes of tummy time per day in the first few months of life, your baby will be spending less time on their backs and will also be developing the neck strength to freely move their head around. Tummy time can be
done on the floor, over a pillow/towel roll, or on a parent's chest.
● Sidelying: During awake time on the floor, support your baby on their side with your hand or by placing a rolled towel behind their back. Encourage reaching for toys in this position and make sure to switch sides after a few minutes!
● Active head movement: When your baby is starting to track objects, encourage them to actively turn their head to the right and left to follow a toy or your face. They may need some help from you until they get stronger!
● Avoid spending time in "containers": Avoid spending more than an hour or two a day in a carseat, swing, or bouncy seat, if possible. Try to hold your baby more often or use a baby carrier if you need to get things done around the house! (Please note that this does not include bassinets or cribs for sleeping).
● Alternating sleep position: Try rotating which end you lie your baby's head down in the bassinet or crib for sleep. If your baby strongly prefers rotating their head in one direction during sleep despite the direction they are placed, try to position their head in the other direction once they fall asleep.
● Avoid "plagiocephaly" pillows: These are being heavily marketed on Facebook and other online sites--these are not approved for safe sleep.
The good news is that as a baby grows and develops in the first few months of life, they will begin to spend less time on the back of their head without any effort from you! By 4-6 months of age, your baby should be rolling onto their tummy independently during floor play and may begin sitting independently around 6 months of age.
What Should I Do if I Have Continued Concerns?
Your doctor may recommend a cranial helmet which would help to promote proper molding of your baby's head as they grow.
Although plagiocephaly may be prevented with the recommendations discussed above, it can persist in some babies and may grow quite severe. Despite an alarming appearance, severe plagiocephaly is considered a cosmetic concern and it should not affect your child's development. Your doctor may recommend a cranial helmet which would help to promote proper molding of your baby's head as they grow. Your doctor may also refer you to a physical therapist to address plagiocephaly, especially if they also notice torticollis, or neck tightness, in your baby. Torticollis and plagiocephaly occur together very frequently and a physical therapist can show you neck stretching and strengthening activities to help address both of these issues.
Your child's pediatrician should screen for plagiocephaly and torticollis at early well-child checks, but always voice any concerns you might have! Early identification and treatment of plagiocephaly and torticollis results in a better outcome for your baby.
