My child moves a lot at night: why, and what to do?

You walk into their room in the morning and your child has their head at the foot of the bed, the duvet on the floor, an arm poking through the bars. If your child moves a lot at night, the first thing to know is this: it is very common, and most of the time it is completely normal. A child who wriggles is not necessarily a child who sleeps badly.

Children’s sleep is nothing like an adult’s. Their nights are made of shorter cycles, with plenty of phases where the body stirs on its own. Moving, turning over, looking for a new position, all of that is part of an ordinary night.

In this article we look at why children move so much, how to tell ordinary restlessness from a real signal worth watching, and above all which small everyday habits can help your child have calmer nights.

Why children move so much at night

Sleep runs in cycles. In a child, one cycle lasts between 45 minutes and a little over an hour, against around 90 minutes in an adult. At the end of each cycle, sleep becomes lighter before dropping back down. That is often the moment when your child turns over, looks for another position, pulls their duvet up or pushes it away.

Then there are dreams. During dreaming sleep, the brain is very active. The body, for its part, can move: small twitches, legs kicking about, changes of position. That is the brain at work, sorting through the day and building memories. There is nothing worrying about it.

Finally, a child has a lot of energy. Even asleep, their body keeps moving, a bit like a small engine still ticking over. The younger they are, the more eventful their nights. It is the sign of a growing body, not of a problem.

• Short sleep cycles, with a lighter phase roughly every hour.
• Dreams that make the body restless at times.
• Plenty of energy to burn off, even during sleep.

When restlessness is perfectly normal

Most of the time, a child who moves at night is doing very well. The best clue is not what happens during the night, it is how they are on waking and during the day.

If your child wakes up in a good mood, has energy, plays, eats and grows normally, then their night time tumbling is most likely just a feature of their sleep. Some children sleep like logs, others turn over all night. Both can be in perfect health.

• They wake up rested, in a fairly good mood.
• They get through the day without being exhausted or grumpy all the time.
• They eat well, play and grow as expected.
• They change position but breathe calmly, without straining.

What can make them move too much

Sometimes the restlessness comes from very simple things that are easy to change. Before worrying, it is worth looking at the mood of the evening and at the bedroom itself.

Heat often comes top of the list. A room that is too warm, a duvet that is too thick, pyjamas that are too heavy, and the child keeps turning over to find somewhere cooler. The right temperature for a child’s bedroom is around 18 to 19 °C.

Evening excitement plays a big part too. A game that gets too lively, an evening that ends in shouting, or a screen just before bed, and the brain stays switched on. Screen light in particular sends the body the wrong signal and delays falling asleep. The result: a more restless night.

• A bedroom that is too warm, or a duvet that is too heavy.
• A screen (tablet, TV, phone) in the hour before bedtime.
• An end of the day that is too exciting, with no quiet time.
• A bedtime that is too late, when the child is already overtired.
• A day with no real burst of energy, where the body has not tired itself out.

The simple habits that calm nights down

Good news: a few regular habits often change a great deal. The idea is not to stop your child moving, but to help them fall asleep more relaxed and stay in deeper sleep.

A regular rhythm is the foundation. A child who goes to bed and gets up at roughly the same time every day has a well set body clock. Their body knows when sleep is coming, and falling asleep happens more easily.

Daytime activity counts just as much. A child who has run about, played outdoors and used their body will sleep more deeply in the evening. Conversely, a day that is too quiet leaves a surplus of energy for the night. But take care not to put that activity right before bed: sport or games that get them going belong earlier in the evening.

Finally, a short, calm evening routine prepares the brain for sleep. Always the same steps, in the same order: the bath, the pyjamas, a story, a cuddle, the lights turned down. That little path reassures them and eases them gently towards the night.

What a pillow that holds its shape does

Here is something people rarely think about: the pillow. Often it is not the child who sleeps badly, nor their bed, it is their pillow. Many children sleep on an adult pillow, too big and too soft for their small neck. The result: the head sinks in, tips to one side, and the child turns over all night to get comfortable again.

A pillow designed for a child is flatter and holds the head at the right height, without letting it drop back or pushing it too high. The foam moulds to the shape of the head, then springs back. Night after night, the pillow holds its shape instead of flattening like an old cushion.

We promise no miracles, and every child is different. But many parents tell us that, once the head is properly held in the right place, their child turns over less and sleeps more calmly. Because the head stays put, the child no longer needs to hunt for a position every five minutes.

At Hushly Kids, the pillow comes in three sizes by age, because a 2 year old neck and a 10 year old neck do not have the same needs: 1 to 3 years (a 2 to 4 cm hollow), 3 to 8 years (4 to 6 cm) and 8 to 14 years (6 to 9 cm). If your child sits exactly between two sizes, you choose by their build, and you have 30 nights to try it at home, with no rush.

When to pay attention and speak to a doctor

Moving at night is almost always nothing to worry about. But some signs are worth mentioning to your doctor or paediatrician, not to make a drama of it, but because they go beyond ordinary restlessness.

Go above all by the daytime. If your child seems exhausted every morning despite fairly long nights, if they are irritable non stop, if they keep nodding off, it is worth raising it.

Some night time signs are also worth a visit: loud, regular snoring, pauses in their breathing during sleep, or difficulty breathing through the nose every night. There, only a health professional can look closely. Do not try to find the answer on your own, and do not try to put a name on what you are seeing: that is the doctor’s job.

• Marked tiredness every morning despite nights of normal length.
• Loud, regular snoring, night after night.
• Pauses in breathing during sleep.
• Laboured breathing, or always breathing through the mouth at night.
• Waking with real pain, or restlessness that clearly gets worse.

Frequently asked questions

Is it normal for my child to move a lot at night?

Yes, it is very common and most often normal. Children have short sleep cycles and plenty of energy, which makes them turn over often. As long as your child is on form on waking and during the day, there is no reason to worry.

At what age does a child move the most at night?

In general, the younger the child, the more eventful their nights. Toddlers and nursery age children often wriggle a lot. It settles down little by little as they grow, as the sleep cycles lengthen.

Can a pillow help my child move less?

There is no promise, every child is different. But many parents tell us that, when the head is properly held at the right height by a suitable pillow, their child turns over less and sleeps more calmly, because they no longer need to hunt for a position all night.

When should you worry if your child moves at night?

If your child is exhausted every morning despite normal nights, if they snore loudly and regularly, if they seem to pause in their breathing or breathe poorly through the nose, speak to your doctor or paediatrician. It is for them to examine your child, without making a drama of it.

Can heat make my child move at night?

Yes, very often. A bedroom that is too warm, a duvet that is too thick or pyjamas that are too heavy push the child to keep turning over to find somewhere cooler. A bedroom at around 18 to 19 °C helps towards calmer nights.
