Child nightmares: what to do when they wake up scared at night

At a glance

• Nightmares are common between 3 and 6, when imagination outgrows a child's ability to keep it in check.
• A nightmare comes in the second half of the night: your child wakes, remembers it and wants comfort.
• Go, stay calm, use few words and stay until they settle.
• In the morning, let them tell it if they want, and change the ending together.
• A calm evening, no scary screens and the same routine make nightmares rarer.

What is a nightmare, and why do they peak around 3 to 6?

A nightmare is a frightening dream that wakes a child, usually in the second half of the night, when we dream most. Your child wakes scared, remembers the dream and wants someone close.

Between 3 and 6 nightmares peak, and the reason is a good one: imagination is growing fast. By day your child invents stories and plays monsters. At night the same imagination keeps going, without them at the wheel, mixing up the day's pieces: a big day at nursery, an overheard argument, a cartoon villain. Their brain is still learning to tell real from made up, and in sleep that line is thinner still.

Nightmares also come more often in times of change: a new sibling, a move, starting school, too little sleep. It doesn't mean you've done something wrong. It means a small mind is working through big things.

How do I tell a nightmare from a night terror?

In a nightmare, your child truly wakes up. They recognise you, can tell you roughly what they dreamed, and calm down in your arms. It usually happens towards morning.

In a night terror, your child looks awake but isn't. They may scream, sit up with eyes open, push you away. They don't recognise you, don't answer, and remember nothing in the morning. It comes in the first hours of sleep and passes on its own within minutes.

What to do then: stay close and keep them safe, but don't try to wake them or ask questions; that drags the episode out. Wait for it to pass and help them lie back down. If episodes are frequent, tell your child's doctor what you saw.

What do I do in the moment, when my child wakes from a nightmare?

When your child cries or calls out at night, go. Don't wait "to see if it stops": your presence comes first. Then:

• Stay calm, even if you're tired. Your child takes their cue from you.
• Use few words: "I'm here. It was a bad dream. You're safe."
• Turn on a low light, not the ceiling light, so they see the familiar room without fully waking.
• Hold them, or put a hand on their back.
• Don't ask about the dream now. This is the moment for comfort, not explanations.
• Stay until their breathing is slow, however long it takes.
• Once they're calm, settle them back into their own bed with their comfort toy.

If they end up in your bed on a hard night, that's not the end of the world. If it becomes a habit, gently walk them back to their own room once they've calmed.

One thing to avoid: a brisk "It was just a dream, nothing happened." For your child, the fear did happen. Better: "The dream is over. The fear was real, but you're safe."

What about the next morning?

In daylight the nightmare is smaller. Ask simply, without pushing: "You got scared last night. Do you want to tell me about it?" A no is fine.

If they do, listen without correcting. Then try dream rewriting: your child draws the dream, then together you draw a new ending where they hold the power. The wolf becomes a puppy, the monster gets a silly hat. At bedtime, remind them: "If the wolf comes, you know what to do: give him the biscuit and he goes away."

The point isn't to deny the fear but to give your child a tool: knowing they can change the ending leaves them less at the dream's mercy. And praise how they handled it: "You woke up scared, called me, and then fell back asleep in your own bed. That was brave."

How can I prevent nightmares?

• Keep the same evening routine, same order, same time.
• No scary cartoons, games or stories, especially in the hour before bed.
• Notice what they overhear: news, arguments, grown-up films.
• Make sure they sleep enough; an overtired child dreams more restlessly.
• Have a "worry talk" earlier in the day, not in bed: "Was anything hard today?" Worries said by day weigh less at night.
• In times of change, expect harder nights and offer more closeness without changing the rules.

Step by step

1. Go as soon as you hear them.
2. Speak softly and briefly: "I'm here. You're safe."
3. Turn on a low light.
4. Hold them until their breathing slows.
5. Don't discuss the dream at night.
6. Settle them back into their own bed with their comfort toy.
7. In the morning, ask if they want to tell you about it. Accept a "no".
8. Draw or rewrite the dream's ending together, and praise the effort.
9. Check the evening: screens, bedtime, routine, worry talk.

By age

• 1–3 years: your child can't describe the dream and doesn't need to. Your presence, a calm voice and the same short sentence are what matter.
• 4–5 years: the peak age for nightmares. Explain simply: "A dream is like a film your head makes while you sleep. When you wake up, the film stops." Drawing and rewriting the ending work well now.
• 6–8 years: your child can talk about what worries them. Agree a night plan (lamp on, hug the toy, three slow breaths, call you) and keep the worry talk for daytime.

Words that help and words to skip

• Try: "I'm here. The dream is over."

• Try: "You got really scared, and that's normal. It will pass."

• Try: "Want to tell me, or shall we just sit together?"

• Try: "Let's give the dream a different ending."

• Skip: a brisk "Nothing happened, go back to sleep!"

• Skip: "You're too big to cry about a dream."

• Skip: "See, I told you not to watch that cartoon."

• Skip: quizzing them about the dream at night.

Common mistakes

• Playing down the fear instead of acknowledging it. Your child learns to hide it.
• Trying to wake or question a child in a night terror. It only lasts longer.
• Turning on every light and starting a long conversation at 3 a.m. Your child then can't get back to sleep.
• Changing the sleep rules after one hard night. One exception is fine; a new habit is hard to undo.
• Blaming your child, or yourself. Nightmares are part of childhood.

When to talk to a doctor or psychologist

Talk to your child's doctor or a child psychologist if nightmares come several times a week for weeks; if your child becomes afraid of going to bed; if they began after a frightening event (an accident, a hospital stay, a loss); if night terrors are frequent; or if your child seems more withdrawn or fearful than usual by day. It isn't a sign you've done anything wrong, just a sensible next step. This article is general guidance, not medical advice.
