Sleepwalking in Children: Causes, Safety and What to Do

It is just after ten in the evening, the supper plates are cleared away – and suddenly your child is standing in the doorway. The eyes are open, the gaze goes straight through you, there is some unintelligible muttering and your child heads for the stairs. There is barely a response when you speak, and the next morning there is no memory of any of it. Sleepwalking in children looks unsettling, but it is one of the most common and most harmless quirks of childhood sleep. Your child is not suffering, is not frightened and remembers nothing – the complete opposite of a nightmare. The key question is therefore not how to make the episodes stop, but how to make your home safe.

The short answer: sleepwalking – somnambulism – is an arousal disorder that arises out of deep sleep and typically happens in the first third of the night, roughly one to three hours after falling asleep. It peaks in the preschool and early school years, and in most children it disappears on its own before puberty. Do not wake your child: speak quietly and guide them gently back to bed. More important than any treatment are enough sleep, regular bedtimes and a secured home.

What is actually happening during sleepwalking

Night-time sleep runs in cycles of around 90 to 110 minutes; in children the deepest sleep sits in the first two or three cycles. During that phase your child sleeps so soundly that they are almost impossible to rouse – and that is precisely where sleepwalking comes from. The specialist literature counts it among the arousal disorders, or parasomnias: parts of the brain switch into waking mode while other parts stay in deep sleep. Your child can therefore get up, walk or open a drawer – while awareness, judgement and memory are not switched on.

The picture many parents describe is typical: open, slightly glassy eyes, a fixed stare, slow movements, sometimes half-sentences that make no sense. Most episodes last from a few seconds to around ten minutes. Afterwards children often lie down again by themselves and sleep on without interruption. Because deep sleep sits in the first third of the night, sleepwalking almost never happens at four in the morning – if your child wakes crying in the early hours, it is usually a nightmare.

How common is sleepwalking in children?

Sleepwalking is far more widespread than most parents imagine. Research suggests that around a third of all children have at least one episode during childhood. Only a small proportion of them sleepwalk regularly, meaning several times a month or more. The peak falls in the preschool and early school years, roughly between 4 and 8 – right in the middle of playgroup, kindergarten and the first school years. With puberty the share of deep sleep decreases, and the episodes then disappear on their own in the vast majority of children.

The family pattern is striking: the specialist literature assumes that sleepwalking is strongly influenced by heredity. If you or your partner sleepwalked as a child, the likelihood in your own child is noticeably higher – and highest when both parents were affected. Do ask the grandparents; «you used to do exactly the same» takes the worry away for many parents. Important: sleepwalking is not a sign of psychological problems and certainly not a parenting mistake. Above all it says something about how deeply your child sleeps and how much sleep they have had in the preceding days – our figures are in our overview of how much sleep children need.

Typical triggers: what makes an episode more likely

Sleepwalking needs two ingredients: the predisposition and a trigger that deepens or disturbs deep sleep. You cannot change the predisposition, but you can certainly change the triggers.

• Lack of sleep. Anyone who sleeps too little sleeps more deeply the following night. After a birthday party or two late evenings, episodes pile up noticeably.
• Irregular bedtimes. If your child goes to bed at 7 p.m. one day and 9.30 p.m. the next, deep sleep keeps shifting. No more than 30 minutes of variation – weekends included – makes a real difference.
• Fever and infections. A temperature from about 38.5 °C changes sleep architecture. Many children sleepwalk only on feverish nights.
• A full bladder. A taut bladder is a classic arousal stimulus. That is why sleepwalking children often end up in front of the toilet. Keeping the last larger drink to around 90 minutes before bed and building a toilet trip into the bedtime routine both help.
• Noise and light. The doorbell, the television next door, siblings going to bed later – anything that disturbs the first third of the night can set off an episode.
• Stress and excitement. Starting nursery, moving up to kindergarten, a house move or a new baby all carry over – not as a «soul problem», but as a more restless night.

One very simple way to see the pattern: for two weeks, note the bedtime, the waking time, anything unusual about the day and any episodes. A clear pattern usually emerges – and often it is enough to bring bedtime forward by 20 to 30 minutes.

Sleepwalking, night terrors, nightmares or sleep talking?

These four phenomena are often confused, yet they call for different responses. Sleepwalking and night terrors are close relatives: both arise out of deep sleep in the first third of the night, and neither leaves any memory. The difference: during a night terror a child screams and struggles violently, whereas a sleepwalker is usually silent on the move. With a nightmare, your child genuinely wakes up, is responsive and seeks comfort. Sleep talking is harmless.

What to do in the moment – step by step

During the episode itself the rule is simple: as little stimulation as possible, as much calm as possible. Here is how to go about it.

1. Do not wake your child. A woken sleepwalker is disoriented and then takes a long time to fall asleep again. No ceiling light, no shaking, no loud calling.
2. Speak calmly and quietly. Short sentences in a low voice: «It's all fine, come on, we're going back to bed.» Do not ask questions – a question demands an answer and wakes your child up.
3. Put yourself between your child and the danger. Stairs, front door, open window: stand in the way rather than pulling your child back. Holding on often provokes resistance.
4. Guide them gently back. A hand resting lightly on the back, steering in the right direction. Most children let themselves be led this way and lie down.
5. Allow a trip to the toilet. If your child clearly wants the toilet, go with them. That often ends the episode straight away.
6. Stay until the breathing is calm. Two to three minutes are usually enough.

The next morning the most important rule is not to make a drama of it. Your child has no memory of the episode, and an excited retelling over breakfast makes it a frightening subject. If your child does hear about it, explain it briefly: «Your body was awake and your head carried on sleeping. It happens, and we're keeping an eye on you.» No reproaches, no interrogation. Discuss the night-time route among the adults – it tells you which spot to secure next.

Common mistakes

• Waking or shaking your child. The most common reflex – and the most pointless. It makes the night longer for everyone.
• Arguing and questioning. «What are you doing?» is well meant, but it drags the episode out.
• Locking the bedroom door. Understandable but dangerous: a locked-in child can panic, or be unable to get out in a fire. Secure the stairs and exits instead.
• Pushing bedtime later so your child is «more tired». The opposite helps: an earlier bedtime, because lack of sleep is the strongest trigger of all.
• Moving your child into the parents' bed. That does not stop the sleepwalking, but it does create a new habit.
• Giving sleeping pills or melatonin. With children this belongs exclusively in medical care.
• Securing only the bedroom. The stairs, the hallway, the front door and the balcony are the places that matter.
• Talking about it in front of your child. Retelling the story over an afternoon snack makes a child uneasy.

When to speak to your paediatrician

Most episodes need no investigation at all. Do get in touch with your paediatrician, though, if any of these applies.

• The episodes happen several times a week or several times in the same night.
• Your child has been injured, has fallen or has left the house.
• Your child is noticeably tired during the day or suddenly needs a nap again at the age of 7.
• Your child snores loudly on a regular basis, breathes through the mouth or has pauses in breathing – enlarged tonsils and sleep-disordered breathing are known contributors and are very treatable.
• The movements look rhythmic, stiff or always exactly the same – these need to be distinguished from night-time seizures.
• Sleepwalking begins for the first time well after the age of 10 or in adolescence.
• It coincides with new bedwetting or clear changes in behaviour.

Helpful for the appointment: a sleep diary covering two to four weeks – and for questions about routines and sleep needs, the Swiss parent and child advisory service is a good first port of call.

Safety checklist: making the night accident-proof

The real risk is not the episode itself, but what a sleeping child can do in an unprepared home. Work through this checklist calmly – ideally in the evening with the lights off, at knee height.

Stairs, doors and windows

• Stair gates at the top and the bottom. Securing only the top is not enough – the lower gate stops your child climbing up and then tripping. Pressure-fit gates do not belong at the top of the stairs; use screw-fitted models there.
• Windows and balcony doors. Lockable window handles or child locks, and do not leave the key in the lock. A tilted window is not a safety measure. No box, no stool, no bed under the window.
• Front door and flat door. An additional bolt or chain at adult height, at least 1.50 m above the floor, with the key out of reach. A door bell or a small door alarm on the frame will wake you.
• Bedroom door ajar, not locked. That way you can hear your child – and they can get out at any time in an emergency.

In the bedroom and along the way

• Clear the trip hazards. Lego boxes, rucksacks, rug edges, cables: the route from bed to toilet should be completely clear at night. Fix rugs down with a non-slip underlay.
• Take the edge off sharp corners. Corner protectors on the bedside table, the desk and the window sill, or better still furniture with rounded edges. Anchor taller shelves to the wall.
• Keep the bed low. The lower the sleeping surface, the more harmless it is to slide out at night. Loft beds are unsuitable for sleepwalking children – in a bunk bed, they sleep on the bottom.
• A night light in the hallway. A dimmed, warm-white light in the corridor and near the toilet gives orientation without waking anyone. More on this in our article on night lights for children.
• Lock hazards away. Household cleaners, medicines, tools and matches in closed cupboards, a guard in front of the wood stove.

If you have a pool, a garden pond or a roof terrace, work through the outdoor areas with the same logic. A complete list for the bed is in our safety checklist for children's beds.

Frequently asked questions about sleepwalking in children

Should I wake my child when they are sleepwalking?

No. Waking your child leaves them disoriented and anxious, and it then takes a long time for them to fall asleep again. Speak quietly and kindly, put yourself between your child and any source of danger, and guide them back to bed with a hand on their back.

At what age do children start sleepwalking?

First episodes usually appear from around 3 to 4 years, once children can climb out of bed on their own. The peak falls between roughly 4 and 8 years. Younger children more often show the night terror, in which they scream but generally stay in bed.

Does sleepwalking go away on its own?

In the vast majority of cases, yes. With puberty the share of deep sleep decreases, and the episodes then disappear as a rule without any treatment. Until then, stable bedtimes, enough sleep and a secured home are enough.

Is sleepwalking in children dangerous?

The episode itself is harmless – it is only the surroundings that are dangerous, because a sleeping child does not register a staircase or the corner of a table. All the effort therefore goes into securing the home: stair gates at the top and the bottom, lockable window handles, an extra bolt at adult height on the front door and a low bed.

Can too little sleep trigger sleepwalking?

Yes, lack of sleep is considered one of the strongest triggers. After a short night your child sleeps more deeply the following night, and that is precisely where the episodes come from. With fixed bedtimes and a bedtime brought forward by 20 to 30 minutes, many parents see fewer incidents within two to three weeks.

Can I lock the bedroom door so my child cannot get out?

No. A locked-in child can panic and would not be able to get out in an emergency. Leave the door ajar and secure the danger spots instead: a stair gate, window locks and a bolt on the flat door at a height of at least 1.50 m.
