Flat Heads in Babies (how to avoid them)

Worried about your baby developing a flat head?

You’re not alone.

It’s one of the most common concerns new parents bring up - often after noticing their baby’s head looking a little… flatter than expected.

The official terms are:

• Plagiocephaly (flat on one side)

• Brachycephaly (flat across the back)

And naturally, the internet is full of “solutions”.

Some helpful…
Some unnecessary…
Some potentially unsafe.

Let’s clear it up.

Myth: You need a special pillow to prevent a flat head

This is one of the biggest misconceptions.

👉 Pillows marketed for flat head prevention are not recommended for sleep.

In fact:

• Babies should always sleep on a firm, flat, clear surface

• Pillows, positioners, and sleep aids can increase the risk of SIDS (sudden infant death syndrome)

So even if a product is:

• widely sold

• well-reviewed

• labelled “safe”

👉 It does not override safer sleep guidance.

Here’s the deal:
If a product says “only use under supervision”…
that means it’s not safe for unsupervised sleep - which is when babies spend most of their time lying down.

And realistically… no parent can supervise every second.

Why do babies get flat heads in the first place?

This is where context matters.

Flat spots have become more common since the “Back to Sleep” campaign (which saves lives by reducing SIDS).

So we have a trade-off:

• babies sleeping on their backs = safer

• but more pressure on the back of the head

Add in modern life:

• more time in car seats

• more time in buggies

• more time placed down

…and less time being held or carried.

What actually helps prevent a flat head?

Not gadgets. Not pillows.

👉 It’s movement, variation, and contact.

1. Hold your baby more than you think you need to

This is the big one.

In many cultures, babies are:

• carried

• worn

• held for large parts of the day

👉 Which naturally reduces pressure on the head.

In the UK, we tend to:

• put babies down more

• rely on containers (car seats, swings, bouncers)

There’s a place for all of those…
but they shouldn’t be the default.

2. Use a sling or baby carrier

This is one of the simplest ways to:

• reduce time lying on the head

• keep baby close

• free up your hands

And it ticks a lot of boxes for bonding too.

3. Give plenty of supervised tummy time

When your baby is awake and supervised:

• tummy time reduces pressure on the back of the head

• strengthens neck and upper body muscles

• supports development

Start small and build up. Stop as soon as baby isn't happy so they don't associate it with a negative feeling.

4. Vary your baby’s position throughout the day

Simple shifts make a difference:

• alternate the direction they lie in the cot

• switch sides when feeding

• encourage head turning both ways

👉 Small, consistent variation beats any product.

“But what if my baby already has a flat head?”

First - relax!

👉 In most cases, flat spots are positional and improve over time, especially as your baby:

• starts rolling

• sits up

• spends less time lying down

If you’re concerned:

• speak to your health visitor or GP

• they can assess whether anything further is needed

What about osteopathy or chiropractic treatment?

You may come across recommendations for:

• cranial osteopathy

• chiropractic adjustments

We've directed thousands of parents at our Expecting Antenatal Classes towards this but more if babies favour turning one way (which can lead to a flat head on one side)

👉 If you’re considering this route:

• choose a qualified, experienced practitioner

• and use it alongside, not instead of, positioning and movement strategies

• If you're local to us, we recommend Village Baby 

The bottom line

Flat heads are:

• common

• usually harmless

• often temporary

And they are not caused by you doing something wrong.

👉 The biggest risk isn’t a flat head…
…it’s unsafe sleep environments created by trying to “fix” one.

Feeling overwhelmed by all the conflicting advice?

You’re not imagining it - there’s a lot of noise out there.

Some of it is helpful.
Some of it is driven by products rather than people.

If you want clear, calm guidance (without the overwhelm), that’s exactly what we support inside our courses and community 💜
