This can feel worrying at first, but in many cases, it’s something that develops due to positioning and can improve over time with the right support.
At One Health Osteopathy Clinic in Tunbridge Wells, we regularly support families across Tunbridge Wells, Tonbridge, Sevenoaks and the surrounding areas who are looking for reassurance and guidance around head shape and positioning.
This guide will help you understand what plagiocephaly is, why it happens, and when you might choose to seek advice.
What Is Plagiocephaly?
Plagiocephaly, often referred to as flat head syndrome, is when a baby develops a flat area on one side of the head.
You may notice:
- Flattening on one side at the back of the head
- A preference for turning the head to one side
- Slight changes in head shape when viewed from above
This is relatively common, particularly in the first few months when babies spend a lot of time lying on their backs.
Why Does It Happen?
A baby’s skull is soft and still developing, which allows for growth but also means it can be influenced by pressure.
Plagiocephaly often develops due to a combination of factors rather than a single cause.
For example, babies may develop a flatter area if they:
- Spend a lot of time lying in the same position
- Have a preference for turning their head to one side
- Have experienced positioning influences during pregnancy or birth
It’s also important to note that placing babies on their backs to sleep, following safe sleep guidance, remains essential and should always be continued.
Is It Something to Worry About?
In many cases, mild flattening is considered a variation of normal development and can improve as your baby grows, becomes more active, and spends more time moving and changing position.
However, parents often choose to seek advice to better understand their baby’s individual situation and how they can support improvement.
How Can You Help at Home?
There are simple ways you can encourage more balanced positioning throughout the day.
This might include gently encouraging your baby to turn their head to both sides, varying how you position them during play and feeding, and increasing supervised tummy time when they are awake.
You can also:
- Change the direction your baby lies in the cot (so they naturally turn their head the other way)
- Alternate sides when feeding or holding
- Use different positions during play to encourage movement
Small, consistent changes can help reduce prolonged pressure on one area of the head.
When Should You Seek Advice?
While many cases are mild, it may be helpful to seek guidance if:
- The flattening seems more noticeable or is not improving
- Your baby has a strong preference for turning their head one way
- You feel unsure about how to support your baby’s positioning
You can speak with your health visitor or GP for initial advice.
Where Does Osteopathy Fit In?
Some parents choose to explore osteopathy as part of a supportive approach when their baby shows a strong positional preference or asymmetry.
Osteopathy focuses on your baby’s movement, comfort, and how they are using their body.
A gentle assessment may look at how your baby moves their head, neck, and body, and whether there are any areas where movement seems more restricted or preferred.
Treatment, where appropriate, uses very gentle, baby-led techniques aimed at supporting ease of movement and comfort.
We also provide guidance on positioning and handling to support your baby at home.
Clinical insight: Osteopathy may support movement and positioning, which can influence how pressure is distributed over time.
Supporting Your Baby’s Development
As your baby grows, becomes more active, and spends more time sitting, rolling, and moving, pressure on the head naturally reduces.
Supporting movement, variation in positioning, and overall comfort can all contribute to this process.
Supporting You as a Parent
Noticing changes in your baby’s head shape can feel worrying, especially when you’re not sure what’s normal.
The good news is that in many cases, plagiocephaly is manageable and can improve over time with simple strategies and support.
If you feel unsure, seeking advice can provide reassurance and help you feel more confident in what to do.
