Nightmares happen when your child wakes while having a bad dream. Your child might remember the 'scary dream' and be afraid to go back to sleep. A reassuring hug will often help them settle back to sleep.
Children can have nightmares at any age. Nightmares are most likely to happen during the later part of the sleep, or in the early morning hours when in Rapid Eye Movement (REM) or Dream Sleep.
Nightmares can be from worries that your child has. It is good to talk to your child about their worries. Children can usually remember these nightmares the next day.
Night terrors happen when children are only partly aroused or woken from deep (Stage N3) sleep. So they are not quite awake, but they are not completely asleep either. Night terrors tend to start in the first 2 to 3 hours after sleep starts and may be at a predictable time each night.
During a night terror your child's brain is asleep, whereas the 'body' looks awake and facial expressions are very emotional. Your child may scream and seem very frightened, usually not recognising the people around them.
It is best not to try wake your child as this might make the episode longer. They may try to run away or push people away.
Night terrors are part of a group of Non-REM sleep arousal disorders or parasomnias.
Your child may remember being frightened, but not what the dream was about. They will not usually remember the night terror the next morning.
Younger children are more likely to have night terrors, and usually outgrow them by the end of primary school age. Like nightmares, there are usually no long-term psychological effects.
With nightmares, it is usually enough to reassure your child and stay with them until they are back to sleep again. Talk about the dream the next day, and ask about any worries or fears that they may have.
A good regular sleep routine and quiet media-free relaxing times before bedtime will help.

With night terrors, your child will appear to be confused and not fully awake, so make your main focus keeping them safe. Make sure the home environment is safe as your child may run around.
When children do mobilise during a night terror, this is sometimes termed 'confusional arousal'. Sometimes children quietly walk during the partial arousal. This is often termed 'sleep-walking'. Together these are thought to represent the same group of partial arousals from deep (N3) sleep.
Lock doors and windows. It's best to sleep on the ground floor.
During the episode, keep your child away from danger by gently restraining them - your child will usually go straight to sleep after a few minutes. Do not try to wake them. This can make the episode last longer.

Before bedtime, try to spend time with your child doing something calm (such as reading a book with them). Try not to watch exciting videos or inappropriate television before bed. For children 12 months and older, avoid food and drinks 1 hour before bedtime.
Things that make night terrors worse include fevers, being tired, or not getting enough sleep. If your child has night terrors, it will help them if you can give them a regular bedtime and wake time (including weekends) to make sure that they get enough sleep. Fevers also make night terrors worse so if they are unwell, try and keep the fever down.

If the night terror happens at the same time every night, you can prevent night terrors by completely waking your child 15 minutes before this time. You could wake them by gently nudging their shoulder until they stir. You can then let them drift off to sleep again.
If they do stop the episodes, after 4 or 5 nights of these scheduled 'wakings', you can stop the waking and see if the night terrors have stopped. In some children, waking them like this may bring a night terror on earlier. So if this happens, go back to not waking them and just making sure they are safe when they have their night terror.
See your doctor if the nightmares or night terrors are:
Your doctor may want to rule out another medical condition related to sleep.
If there is an underlying cause, this may need treatment before the night terrors will stop. Underlying causes include snoring and sleep apnoea, or periodic limb movements. These will need treatment. Treatment has been shown to almost completely get rid of night terrors. Even if your child does not have another condition, extra measures may be needed, including:
Sleep disorders are very common in childhood and fortunately most of the time there are no underlying medical conditions. Your family doctor will be familiar with these problems and can offer help.
