Why Do Babies Get Bald Spots From Sleeping?

You put your baby to bed.

Everything looks normal.

And then one day, you suddenly notice it:

a bald patch at the back of the head.

Or maybe on one side.

And naturally, your brain goes to:

“Wait… is this normal?”

The reassuring news?

In many cases, yes — baby bald spots from sleeping are extremely common.

And most of the time, they happen because of rubbing.

Because babies spend so much time lying down, delicate hair repeatedly moves against the same sleep surface.

Over time, that friction can gradually wear hair away.

Parents often describe it as:

“It looks like the hair has rubbed off.”

And honestly? That’s often exactly what’s happened.

Can Sleeping Really Cause Baby Bald Spots?

In many cases, yes.

Not because sleep itself is harmful.

But because sleep involves lots of repeated movement.

Babies naturally turn their heads, shuffle, wriggle and move side to side.

And because they spend so many hours resting on the same surface, friction builds up.

A young baby may spend 12–16+ hours sleeping, plus additional time resting during the day with the same area touching fabric.

That repeated movement can gradually wear away very fine baby hair.

This is why parents often notice hair loss exactly where the head touches most.

• the back of the head
• one side
• a favourite sleeping position

Why Does It Usually Happen At The Back Of The Head?

Because that’s usually where the rubbing happens most.

Babies spend much of early life lying on their backs.

This is completely normal and recommended as part of safer sleep guidance.

But it also means the same patch of delicate hair repeatedly rubs against fabric.

Over time, that rubbing adds up.

Many parents first notice a thinner patch, hair looking flatter, a rubbed-looking area or hair disappearing in one spot.

Then suddenly think:

“Oh wow… when did that happen?”

But because rubbing happens gradually, it often sneaks up on parents.

What Is Friction Hair Loss?

Friction hair loss is exactly what it sounds like:

hair gradually rubbing away through repeated movement against fabric.

In babies, this is very common because their hair is:

• extremely fine
• delicate
• still developing
• easily affected by rubbing

And babies spend huge amounts of time with their head against fabric.

This is why many parents start paying closer attention to sleep surfaces, bedding, fabrics, bouncers and chairs — anywhere hair repeatedly rubs.

Why Do Some Babies Get Bald Spots More Than Others?

Some babies seem to lose hardly any hair.

Others get noticeable bald patches quite quickly.

A few things can play a role.

1. Some Babies Move More

Some babies are little wrigglers.

Constantly moving their heads, turning side to side and rubbing during sleep.

More movement can mean more friction.

2. Hair Type

Some babies simply have finer or softer hair, which may rub away more easily.

Some babies are also born with thicker hair that appears less affected.

3. Favourite Sleeping Position

Some babies naturally favour one side.

This can create more repeated rubbing in the same spot.

4. Time Spent On Their Back

Young babies spend lots of time lying down.

Not just sleeping.

Also in bouncers, swings, loungers, car seats and play mats.

All of this can contribute to repeated rubbing.

Does Bedding Play A Role?

Yes — often a very significant one.

Because for many babies, the bedding is where most rubbing happens.

Think about the amount of time babies sleep.

That’s many hours every day where the same area of hair moves repeatedly against fabric.

This is one reason many parents begin paying closer attention to what their baby sleeps on.

Especially once they notice:

“the hair seems rubbed away.”

Bedding isn’t always the only factor.

But for many babies, it’s one of the biggest sources of friction.

Why Some Parents Switch To Silk Bedding

Once parents realise:

“This is probably friction…”

the next question usually becomes:

“How do I reduce the rubbing?”

This is where silk often enters the conversation.

Compared with traditional cotton, silk has a much smoother surface.

Hair glides more easily across it, which means less resistance during movement.

This is actually the same reason silk pillowcases became popular for adults.

Less friction. Less pulling. Smoother movement.

For babies, the idea is similar.

If hair is rubbing against fabric for many hours every day, a smoother sleep surface may simply make sense.

It’s Not Just The Cot Mattress

One thing many parents realise is that the rubbing happens everywhere.

Not just overnight.

Parents often notice friction in:

• baby bouncers
• swings
• car seats
• loungers
• chairs

Anywhere baby’s head repeatedly moves against fabric.

A trick many parents love?

Using a smooth silk pillowcase over the fabric area where baby’s head rests most during awake time — especially for bouncers and baby chairs.

For this, many parents use our adult silk pillowcase, because the larger size can be easier to position over wider bouncers, chairs or loungers.

Always keep this for supervised awake time only. For sleep, always follow current safe sleep guidance.

Will My Baby’s Hair Grow Back?

In many cases, yes.

As babies grow, they move more, sit up, spend less time lying down and friction naturally decreases.

Often, hair starts growing back naturally.

For many families, the bald spot stage is temporary.

When Should Parents Be Concerned?

Most baby bald spots are very normal.

But speak to a healthcare professional if you notice:

• redness
• irritation
• broken skin
• scaling
• unusual patches
• severe or sudden hair loss
• baby seeming uncomfortable

A rubbed bald spot from sleeping is usually nothing to panic about.

But trust your instinct if something feels off.
