It's two in the morning. Your child starts screaming, sitting up in bed, eyes wide open — but they don't answer you. You talk to them, you take them in your arms, and nothing works. Your heart races, you feel lost, and you wonder what's going on. If you've already lived this, you're not alone — and above all, it isn't your fault.
This moment of panic often has a name: a night terror. And it isn't the same thing as a nightmare, even if from the outside they can look alike. Understanding the difference changes a lot, because the right reaction isn't the same in both cases.
In this article, we explain in simple words what happens in your child's head, how to tell a night terror from a nightmare, what to do during, what to do after, and how to help these nights become calmer. We also tell you, without dramatizing, when it's better to talk to a doctor.
Night terror or nightmare: they're not the same
This is the first thing to understand, and it clarifies everything else. A night terror usually happens early in the night, in the deepest sleep. The child seems agitated; they may scream, cry, sit up, have their eyes open. But they're still asleep. They don't recognize you, they don't answer, and the next morning they remember nothing at all.
A nightmare, on the other hand, usually comes late at night, toward early morning. There, your child really wakes up. They've been scared, they cry, they look for you, and they can tell you about their bad dream. The next day they remember — sometimes they even talk about it during the day.
This difference isn't a detail. Facing a night terror, you stay calm and wait for it to pass. Facing a nightmare, you comfort and reassure. We cover both reactions below.
- A night terror happens early in the night; a nightmare more toward morning.
- During a terror, the child is still asleep; during a nightmare, they're fully awake.
- During a terror, they don't recognize you and don't calm down when you talk to them.
- After a terror, they remember nothing; after a nightmare, they remember and tell the story.
- A terror mostly worries the watching parent; a nightmare is the child who's afraid.
Why does it happen?
The good news is that these episodes don't mean something is wrong with your child. They're very common, especially between ages 3 and 6, and they're part of sleep that's still settling in. Often there isn't even a precise reason.
That said, some things often come up when nights get restless. They aren't serious, and most settle with a little attention to the rhythm of the days.
Here's what often helps a night terror or nightmare take hold. Spotting one or two in your child's life is already a lead toward calmer nights.
- Built-up tiredness, when they've been short on sleep for several days.
- A big change: starting school, a move, a little sibling, holidays.
- Too many screens, especially in the evening, which wind up the mind just before bed.
- Bedtime that's too late, or nights that are too short for their age.
- A spell of fever, a cold, or a day really packed with emotions.
What to do during a night terror?
This is the most striking moment, so we'll get straight to it. During a night terror, your child is asleep, even if everything seems to say otherwise. Waking them suddenly doesn't help, and often leaves them even more lost. The best thing is to stay near them and wait.
Keep your calm, even if it's hard to see them like that. The episode usually lasts a few minutes, then your child lies back down and falls asleep on their own, as if nothing happened. The next day they won't remember anything — and that's very good.
What to do after a nightmare?
A nightmare is the opposite. There, your child is awake, they're truly scared, and they need you. This is the moment to comfort them, simply. Take them in your arms, speak softly, let them nestle against you until the fear comes down.
No need for long explanations in the middle of the night. Simple words are enough: "I'm here," "you're safe," "it was only a dream." A little night light, their comfort toy, a sip of water — and often the night gently resumes. The next day, if they bring it up, listen without making a big story of it.
Also think to check something very basic: are they too warm? A room that's overheated, a duvet that's too thick — and sleep gets more restless. A child who's cool, with their head well placed, often sleeps more peacefully.
How to help these nights become calmer
You can't prevent every night terror or every nightmare — and that isn't the goal. But when a child sleeps in good conditions, these episodes often become rarer. It mostly comes down to bedtime and the rhythm of their days.
The general idea is simple: a rested child, put to bed at regular times, in a calm bedroom, sleeps more deeply and more quietly. Nothing complicated — just a few gentle habits to put in place little by little.
And what about bed comfort in all this?
Let's be clear right away: a pillow doesn't make night terrors or nightmares disappear. That isn't the point, and no one should sell you that. These episodes come mainly from tiredness, emotions, and sleep that's still maturing.
What bed comfort can do is help your child sleep more quietly in general. A cool room, a suitable duvet, and a head well placed through the night. For an older child, a pillow in their size keeps the neck in a more natural line, instead of a head sunk or twisted all night.
Many parents tell us that a well-settled child moves less and sleeps more calmly. We promise nothing more than that: comfort. For restless nights that keep coming back, it's the rhythm of the days — and if needed, a doctor's advice — that matter most.
When to talk to the doctor
Most of the time, night terrors and nightmares pass on their own with age, without anyone needing to step in. It isn't serious, and it isn't a sign of a problem. So keep your calm and let time do its work.
That said, there are cases where it's a good idea to mention it to your doctor or pediatrician, calmly. Not to worry, but to be well supported and ask the right questions.
- The episodes come back almost every night for several weeks.
- They last a long time, or your child seems truly exhausted the next day.
- They often put themselves in danger at night — get up, walk, bump into things.
- You notice something else that worries you in their sleep or their days.
- You feel, as a parent, that something isn't right: your judgment counts.
