The Child Who Walks at Night

It is quarter past ten. Your seven-year-old is standing at the top of the stairs, eyes open, hand on the bannister, quietly telling you that the shoes need to go in the car. Tomorrow morning, she will have no idea this happened.

What is actually going on

Sleep is not a single state. In the first couple of hours after falling asleep, children drop into deep slow-wave sleep — the heaviest sleep they get, and proportionally far more of it than adults. Sleepwalking occurs when the body partially surfaces out of that deep sleep while the parts of the brain responsible for awareness and memory stay offline.

The result is a child who can walk, open doors, speak in fragments and appear awake, while being neurologically nowhere near it. Because memory is not running, nothing is recorded. This is why the morning question 'do you remember last night?' produces a blank stare — and why asking it repeatedly can make a child anxious about sleep for no benefit.

What to do in the moment

1. 01Do not try to wake them. Waking a child from deep sleep produces confusion and distress, and can make the episode longer.
2. 02Speak quietly and neutrally, and guide them back by the shoulders or hand.
3. 03Do not argue with the content. If they say the shoes need to go in the car, 'we've done that, come on' is enough.
4. 04Stay until they are settled. They will usually lie down and return to sleep within a minute or two.
5. 05Say nothing in the morning unless they raise it, and if they do, be light about it.

Reducing how often it happens

Sleepwalking is a pressure phenomenon. The more sleep debt a child carries, the deeper and more unstable their slow-wave sleep becomes, and the more likely an incomplete arousal is. Almost everything that reduces episodes works through the same mechanism.

• Consistent bedtime and wake time, including weekends — irregularity matters as much as lateness.
• Enough total sleep for age: roughly 10–13 hours for three to five year olds, 9–12 hours for six to twelve year olds.
• Empty bladder immediately before bed; a full bladder is a well-documented trigger.
• Screens off well before sleep, and a genuinely dark, cool room.
• Manage daytime worry — anxiety fragments sleep, and fragmented sleep invites episodes.
• Expect a flare during illness, fever, travel or the first weeks of a new school year.

Scheduled awakenings

When episodes are frequent and happen at a predictable time, a behavioural technique called scheduled awakening can help. Track the timing for a week or two, then gently rouse the child — just enough to stir, not to fully wake — about fifteen to thirty minutes before the usual episode, every night for a few weeks. This nudges them out of the deep-sleep phase where the arousal occurs.

It works best when episodes are consistent in timing, and is worth discussing with your GP or a sleep clinic first, particularly if your child is already an unsettled sleeper.

When to seek advice

Sleepwalking is common and usually benign, but speak to a GP if episodes are very frequent, if your child leaves the house or has been injured, if they occur many times a night, if there is loud snoring or observed pauses in breathing, if the child is excessively sleepy during the day, or if any unusual movements or stiffening make you wonder about seizures. These are checks, not alarms — most result in reassurance.
