Night terrors in infants – What they mean and how to help
Night terrors in infants are sudden, intense episodes of waking, crying, or confusion that most often occur in the first half of the night. While these events can be frightening for parents, night terrors themselves are not a sign of serious illness and rarely cause long-term problems.
It’s important to know that night terrors are not the same as nightmares. During a night terror, your baby does not fully wake up, is difficult to comfort, and will not remember the event in the morning. This phenomenon is a normal part of sleep development in babies and young children, and usually resolves on its own.
What are night terrors? 💤
A night terror is a sleep disturbance where your child suddenly sits up, may scream or appear confused, but does not fully wake. Their face may show fear or confusion, their heart rate is faster, and they are hard to soothe. Episodes typically last 1–10 minutes before your child settles back to sleep.
How are night terrors different from nightmares?
- Night terror: Child does not fully wake, no memory in the morning, hard to comfort.
- Nightmare: Child wakes up completely, remembers the dream, easier to comfort.
What causes night terrors in babies?
The exact cause of night terrors is not fully understood, but several factors may contribute:
- Sleep cycle development: Babies’ brains are still learning sleep stages, which can lead to temporary disruptions.
- Overtiredness or irregular sleep: Night terrors are more common if your child is very tired or has an inconsistent sleep schedule.
- Illness or fever: Colds, fever, or other illnesses can trigger episodes.
- Stress or changes in environment: New surroundings, family changes, or travel can temporarily affect sleep.
The biology behind night terrors
Night terrors happen during deep non-REM sleep, when brain activity is low but the body may suddenly react to internal or external triggers. The nervous system gets temporarily “confused,” so your child cannot fully wake up, but their body shows signs of stress (fast heartbeat, sweating, movement).
This process is not a sign of a neurological disorder, but a normal part of sleep development, especially between 6 months and 3 years of age.
How to recognize night terrors in your baby
- Your baby suddenly sits up, cries, but does not respond to your voice or touch.
- Their face looks scared, eyes may be open but seem “blank.”
- The episode lasts a few minutes, then your child lies back down and continues sleeping.
- In the morning, they have no memory of the event.
A typical example: Your 1-year-old sits up and cries at 2 a.m., but does not fully wake. You try to comfort them, but they do not respond. After 5 minutes, they settle and sleep peacefully.
What can parents do? 👶
- Stay calm: Night terrors are not dangerous and do not cause pain.
- Do not force your baby to wake up: Keep them safe from injury, but avoid waking them abruptly.
- Ensure a safe sleep environment: Remove hard objects and sharp corners near the bed.
- Monitor sleep routines: Try to keep a regular schedule so your child is not overtired.
- Track episodes: If night terrors are frequent, note the times and details to share with your doctor if needed.
Risks and when to seek medical advice
Night terrors are usually harmless, but rarely, a child may get hurt (falling out of bed, bumping into objects). See your pediatrician or a sleep specialist if episodes are:
- Very frequent (several times a week)
- Prolonged (lasting more than 10 minutes)
- Causing daytime changes (anxiety, fatigue, irritability)
- Or involve risk of injury
When is it NOT a cause for concern?
If night terrors are rare, brief, and your child is happy and balanced during the day, there is no need to worry. Most children outgrow night terrors as their nervous system matures.
