What is Baby Flat Head Syndrome, and the Best Pillows to Prevent It?

Have you noticed a flat or indented spot on your baby’s head that has you concerned? You may have taken your little one to her doctor only to hear that your baby has flat head syndrome and that it is nothing to worry about. But as a parent, that is easier said than done, especially when you notice an abnormality with your precious little baby.

So, what is flat head syndrome, and can something be done to prevent or reverse it?

We are here to help you through this, answering your questions and concerns, and giving you some options that will keep your baby happy and ease your mind.

What is it, and What Causes it?

Have you ever put your hand on the back or top of a newborns head and felt a gap in their skull (often known as a soft spot? That is because babies are born with soft heads. Their skulls are not like ours (solid, in one piece), but rather they are in several pieces to allow movement as they are developing.

Babies’ skulls are like this for two reasons:

First, your child’s brain grows at a tremendous rate over the first three years of her life. When she is born, her brain already has about all the neurons it ever will. By the end of her first year, her brain will double in size, and by age three it will already be about 80% of its adult volume. With all that growth, the skull needs to remain flexible so that brain growth in not restricted.

Second, the separation in your baby’s skull allows for easy molding and flexibility when descending through the birth canal. Imagine if your baby’s skull was solid. There would be no way for her to pass through without major damage to you or herself, if she could even pass at all.

Now, even though baby’s skulls need to be softer for these reasons, it can also cause them to be misshapen due to birth or the position they lay in. Due to pressure on the skull from these things, babies may develop a flat spot on their skull, developing what is known as Flat Head Syndrome, or Positional Plagiocephaly.

Is it Dangerous?

Most cases of positional plagiocephaly are not dangerous. They do not cause any problems with brain development, and are actually very common. However, you should still see your pediatrician if you notice flat spots on your baby’s skull so that she can keep an eye on the baby’s development.

In some cases, this condition will affect your baby’s neck and her range of mobility. This is known as torticollis. It is usually caused by severe head flattening in one area, which can cause your baby to stay laying on that one area and develop a stiff neck.

In some rare cases, this can also develop in the womb. If a baby is too cramped for an extended period of time, it can cause head flattening and not allow proper neck movement. While torticollis can be difficult to overcome (you know the feeling if you have ever woken up with a stiff neck), it is also something that is easily treated with proper care and resolved over time.

Your doctor will be the one to diagnose the problem, if it is flat head syndrome, and to what degree the flatness may affect your baby. She will check for the baby’s head and neck movement, and will continue to monitor her over the next several visits.

How to Treat Flat Head in Babies

Most cases of plagiocephaly heal themselves over time, especially when they are caught when the baby is still young and the skull is still soft, but there are things that you can do to help the reshaping process, or at least keep it from getting worse.


Change Your Baby's Position During Sleep

A big part of the reason that babies develop flat head syndrome is due to the fact that they are always on their backs, especially when they sleep. It is important to keep your baby in this position as it reduces the risk of suffocation from lying on the stomach and SIDS.

However, you can reposition your baby’s head while she sleeps to keep flattened areas from getting flatter. Turn your baby’s head from side to side, allowing the flat part to be off the mattress so that it can round itself out again.


Incorporate Lots of Tummy Time into Your Day

I am very thankful that my baby did not develop flat spots on her head (despite being born with a “cone head” which lasted for the first few days), and I believe this is because she did a lot of tummy time.

Tummy time (which should always be supervised) is the best way for your baby’s head shape and neck strength to develop properly. This will be key for later development, which will involve crawling and sitting up on her own.


Severe Cases May Require a Helmet

There are severe cases of plagiocephaly that require some extra treatment in order to round out the baby’s head. If your baby’s flat head syndrome is severe and does not get better after 2-3 months of repositioning at home, your doctor may prescribe a helmet for your baby to wear.

They typically work best between the ages of 4-12 months, when the bones are still moldable and your child is still growing at a fast rate. By applying gentle but constant pressure on the baby’s skull, the helmet helps to redirect the bones and promote rounding.


A Cheaper Alternative: Baby Head Shaping Pillow

For cases that may not be severe but need a little extra help, you can look into getting your baby a pillow especially designed for rounding out the shape of her head. These are much less expensive than baby helmets (which can run thousands of dollars and are often not covered by insurance) and much more comfortable for your baby.

What to Look for in a Pillow

Most pillows are very comparable to one another, so how do you choose the best one?

Looking for these features will help you to narrow down your selection and get the right pillow for your baby:


Babies have very sensitive skin, and certain fabrics, dyes, chemicals, and detergents that do not bother us adults can cause rashes and breakouts in young babies.

When it comes to products that will come into contact with your baby’s skin, you are best opting for something organic or hypoallergenic. This will keep your baby’s skin happy and clear of any rashes due to irritants.


As babies grow, their skulls will become more solid, and their necks and spines will strengthen so they can support their own weight. As such, most babies will not need a shaping pillow beyond about 6 months of age.

However, not every baby is the same. Those soft spots in their skulls can remain beyond one year (my daughter was 14 months old with her tiny little soft spot still on the top of her head). If you choose to use the pillow for naps and bed time, you will want to find one that can still fit your baby as she gets older.

Easy to Clean

Babies are messy and unpredictable, with fluids coming out of both ends that could ruin anything they come into contact with. Their clothes and bedding will need to be washed regularly due to spit up and diaper blow outs.

The last thing you want is to have a pillow that is a hassle to wash. Even though hand washing and air drying may be alright for some items in your household, you will want things that are machine washable for your baby, that way you can spend more time with her and have her things ready quicker rather than waiting for them to air dry.

Allows Movement

Even though baby pillows are meant to support their heads and prevent flat spots from forming on their skulls, there also needs to be a certain degree of movement allowed with the pillow.

Babies still need to be able to move their heads from side to side. This will help to prevent a stiff neck and promote proper development of the neck and spine. She will also need to be able to move her head in case she spits up while lying on her back so she does not choke.

A Word of Warning!

While most cases of positional plagiocephaly occur as the result of pressure on the baby’s head while sleeping, the American Academy of Pediatrics does not recommend using a positioning pillow in the baby’s crib while she is sleeping.

Any soft or bulky items, like pillows, blankets, or stuffed animals, left in a baby’s crib are suffocation hazards, especially if your baby has begun to roll on her own. If you do choose to use a pillow to help shape your baby’s head in her sleep, please only do so during naps when she can be constantly supervised.

Instead, we recommend using these pillows for play time during the day when your baby is awake, supervised, and aware of what is around her. Some of them are best used in swings and strollers, and others are great for use with floor gyms.

  • Baby may slide: with its wedge shape, younger babies may need to be readjusted on the pillow as they wriggle and slide down.

Breathable fabric

If your baby is like mine, she gets hot very easily. She may need minimal clothing and blankets when she sleeps, as too much will turn her into an unhappy, sweaty mess. This pillow from WelLifes is perfect for babies like mine as it is breathable and keeps your baby cool.


  • 2 available shapes and several designs: there are two available shapes for this pillow – one that can be used flat on the floor or in a crib, and one that can bend a bit more to fit in strollers and car seats for head and neck support. With all the great colors and designs, you are sure to find something that fits your personal taste.

    Organic and hypoallergenic: made from organic cotton, this pillow is great for babies with sensitive skin as it reduces irritants that may cause rashes and breakouts.


  • Not recommended for older babies: this pillow can be a bit small for babies older than 4 or 5 months. Since they are more mobile – kicking and starting to roll – they may fall off the pillow and need to be repositioned often.
  • close
    Requires care when washing: this pillow is not a simple wash and go product. It is recommended to hand wash in cold water and keep away from heat, like dryers and irons.

Great portable option

If you are a mommy on the go, your baby will be spending a lot of time in the stroller. You will need a pillow that can travel with you, so that the pressure of sitting in the stroller does not flatten your baby’s head while you are out and about.

    Small for older babies:this pillow runs a bit small, and is advertised to fit babies up to 4 months old. If your baby needs additional support in later months, you will need to buy a new pillow or insert that will fit her better.

    Not recommended for car seat use: while this pillow is good for stroller use, it is not recommended for car seat use, since it does not have neck support for the amount of movement a car makes.

    Machine washable:this pillow can easily be washed and dried by machine due to its durable polyester fabric.

  • close
    Does not work well with older babies: babies who are starting to roll run the risk of suffocation or injury with this pillow by rolling face down on it or rolling off.
