When to change your child's pillow: the signs to look for

You are tidying the bed one morning and the question comes to you without quite knowing why. Is this pillow still right for your child? They have had it a while, it has gone rather flat, and your little one wakes up sideways across the bed with their head off to one side. You wonder whether it is time for a new one, or whether you are imagining things.

Good news, there is no mystery to it. A child’s pillow gets replaced for two very different reasons, and once you know them, it all becomes easy to spot. The first is that your child is growing, and their little neck needs a bit more height than before. The second is that the pillow itself wears out over time, like a mattress or a pair of shoes.

In this guide, we go through the very simple signs to watch for, the everyday ones you already see without thinking about them. You will learn to tell a worn pillow from a pillow that has become too low for your child, how often to think about it, and how to move on to the next one without it turning into a drama at bedtime.

Two reasons to change, not to be confused

Before looking at the signs, the two cases need to be kept apart. They are not the same thing, and the solution is not the same either. People often mix the two up, and end up buying the wrong size or keeping a tired pillow for too long.

First case, your child has grown. The pillow is in good condition, but it has become too low for them. Their shoulders have widened, their neck needs a bit more height to stay properly in line. Here you do not replace it with the same one, you move up to the size above.

Second case, the pillow has worn out. It has had its day, it no longer holds the head properly, it stays squashed in the morning. The size may well still have been the right one, but the filling no longer keeps up. Here you buy the same model again, in the size that suits their age at the time.

The signs that the pillow is worn out

A child’s pillow goes through a lot. It is chewed, sweated on, squashed and cuddled all year round. At some point it tires, and it shows. Here are the signs that come up most often with parents. If there are one or two, keep an eye on it. If they add up, it is time to change it.

• It stays completely flat in the morning and no longer springs back, even after you have plumped it.
• It has yellowed, it has marks that no longer come out in the wash, or it keeps a smell even when clean.
• It has lumps, clumps or hollows, the filling no longer spreads evenly.
• It folds in half on its own, without holding up, when it used to stay upright.
• Your child complains about it, or pushes it away, when they used to be quite fond of it.

The signs that the height no longer works (they have grown)

Here the pillow can still be perfectly clean and in good condition. The trouble is that it has become too low for your child, who has shot up. The body says so in its own way, at night, without words. These are small movements you have almost certainly noticed already without paying attention to them.

• They slip their arm, their hand or their comforter under their head to raise it.
• They hunt for a position, turn over a lot, end the night sideways across the bed.
• They push the pillow away or sleep next to it, head flat on the mattress.
• They wake up with a pulling feeling in the neck, or complain of feeling uncomfortable on waking.
• Their head looks sunk too deep into the pillow, or on the contrary lifted a little too high.

How often should you think about it?

There is no ready-made date on the calendar, and be wary of the overly precise figures you see quoted here and there. Every child wears their pillow out at their own pace, depending on whether they sweat a lot, chew it, or move about all night.

In practice, two simple markers are enough. For wear, take a proper look at the pillow at every change of season, when you get the duvet out again or when you strip and remake the bed. If it stays flat, if it smells despite washing, if it goes lumpy, that is the moment.

For height, you come back to it mainly when your child moves from one broad age bracket to another, around 3 years old, then around 8 years old. Between those stages, the same size does the job perfectly well. The real signal is not the age printed on the box, it is what your child does at night.

Moving up to the size above as they grow

When it is the height that no longer works, you do not buy the same pillow again, you go up a size. It is like shoes, a model that is perfect at 3 years old becomes too flat at 6 or 7. The shoulders widen, the gap to fill between the shoulder and the head gets bigger, and a bit more support is needed to keep the head straight.

The three sizes follow your child as they grow. The lowest one for the very little ones, a medium height for school age, a bigger one for pre-teens. You choose by age first, then adjust for build, because a sturdy child can move up to the size above earlier.

• 1 to 3 years: the very first pillow, nice and low, for a small neck.
• 3 to 8 years: a bit more height, for shoulders that are widening.
• 8 to 14 years: the largest format, for a broader neck.
• A child right between two sizes: look at their build, slight means staying low, sturdy means going up a notch.

Hygiene, sweat and tiny creatures

There is also a reason that often gets forgotten, and that is cleanliness. A child sweats at night, dribbles a little, breathes on it for hours. Over time, a pillow that has seen a lot of use holds moisture, and that is a spot dust mites are fond of. These are the tiny invisible creatures that can bother a sensitive child and tickle their nose.

No need to panic, most of the time good care is enough and there is no rush. You air the room every morning, wash the pillowcase often, shake the pillow out in the fresh air. But when a pillow is years old, when it smells despite the washes or when it yellows, replacing it does everyone good, especially a child with an itchy nose.

Changing the pillow gently

A child gets attached to their pillow the way they do to their comforter. The new one smells different, it is firmer, the head does not settle the same way. It is no surprise if they pull a bit of a face for the first few nights. Give them time, a few nights are almost always enough.

To make it go smoothly, present the new pillow as a lovely new thing, not as a chore. Keep the same pillowcase if they like the pattern, it is a familiar marker that reassures them. You can also offer it on a calm evening, with nothing else changing in the room at the same time. A child who pushes their pillow away on the first night has not said no forever.

Many parents tell us that after a few nights, their child moves about less and wakes up feeling better, once the head is properly supported at the right height again. Every child is different, but giving them that time to adjust often changes everything.

The safety reminder for the very little ones

One important word before we finish. Everything we have just covered concerns a child who is already old enough for a pillow, generally from 2 years old. For a baby under 1, there is no pillow to change, because there is none at all. A very young child sleeps flat, on their back, on a firm mattress, with no cushion near their face.

And if your child’s sleep genuinely worries you, loud and constant snoring, pauses in their breathing, tiredness that drags on during the day or neck pain that keeps coming back, this is not a pillow matter. Make an appointment with your doctor or your paediatrician, who will be able to answer you far better than a change of bedding.

Frequently asked questions

How often should a child’s pillow be changed?

There is no fixed date, every child wears their pillow out at their own pace. Check its condition at every change of season. If it stays flat, if it smells despite washing or if it goes lumpy, that is the moment. For height, you come back to it mainly when your child moves into a new broad age bracket.

How can you tell whether the pillow is worn out or just too small?

Look at the condition first. If it stays squashed, if it yellows, if it goes lumpy, it is worn out, and you buy the same model again. If it is in good condition but your child props their hand under their head or sleeps sideways across the bed, they have grown and they need the size above.

My child puts their hand under their head at night, is that serious?

It is not serious, but it is often a sign. When a child slips their hand, their arm or their comforter under their head to raise it, it means their pillow has become a little too low for them. A slightly higher model lets them rest their head without having to prop themselves up on their own.

Does the pillow need changing as the child grows?

Yes, just as with shoes. A pillow that is perfect at 3 years old can become too flat at 6 or 7, because the shoulders widen and the neck needs a bit more height. You then move up to the size above, choosing by age and then by the child’s build.

Can an old pillow bother a child with an itchy nose?

A very old pillow holds moisture and dust mites are happy in it, which can tickle a sensitive child’s nose. A clean pillowcase every week and a good airing in the morning help a great deal. If the runny nose or the morning sneezing carries on, speak to your doctor.
