Nightmares and night terrors in toddlers

Nightmares first show up between 2.5 and 3 years and can last for years. Here's the difference between nightmares and night terrors — and what actually helps.

Nightmares vs. night terrors — they're different things

They're often confused, but the way you respond to them is opposite.

Nightmares

• Happen in the second half of the night (3–6 AM)
• Occur during REM sleep
• The child wakes up and remembers the story
• Can tell you what they dreamed, needs comforting
• Hard to fall back asleep

Night terrors (sleep terrors, parasomnia)

• Happen in the first 1–3 hours after falling asleep
• Occur during deep non-REM sleep
• The child does NOT wake up — their eyes may be open, but they don't recognise you
• Screams, cries, may run around or thrash — but is "asleep"
• Lasts 5–15 minutes, ends on its own
• In the morning they remember nothing

What triggers nightmares and how to reduce them

Triggers (avoid in the 2 hours before bed):

• Scary cartoons, videos, stories
• Scenes of aggression or chasing
• Loud, energising music
• Family conflict, shouting
• Unfamiliar noisy places (just got home from visiting)
• Hunger or, on the flip side, overeating before bed
• A bedroom that's too warm (above 22°C / 72°F)

What helps prevent them:

• A consistent ritual — the brain learns "after bath comes sleep"
• A "protector" in bed — favourite stuffed animal
• A nightlight with warm yellow light (not blue or white)
• Door cracked open — they can hear parents' voices
• Monster spray — water with lavender in a spray bottle, ritually "spray" the room before bed
• A "dreamcatcher" above the bed — the folklore that bad dreams get caught in it

How to soothe after a nightmare (at night)

1. Turn on a warm light (not bright)
2. Hug them, say "it was just a dream, you're safe, mum/dad is here"
3. Don't quiz them about the dream — that locks the image in
4. You can offer some warm water to drink
5. Stay for 5–10 minutes, rub their back, hum quietly
6. Only leave once their breathing has evened out

What to do the morning after a rough night

Talk about the dream calmly over breakfast. Let the child "chase off" the fear:

• Draw the monster and tear up the drawing
• "Put" the fear in a little box and store it on a high shelf
• Invent a funny ending for the scary dream ("…and then the monster slipped on a banana peel…")

When to see a specialist

• Nightmares or terrors happen more than 3 times a week for a month
• They're accompanied by seizures, wetting the bed, heavy sweating
• The child is afraid to fall asleep, cries, refuses to go to bed
• They started after a traumatic event (divorce, a move, illness)
• Heavy daytime sleepiness, the child "switches off"

The link with routine and lack of sleep

Here's the paradox: the more sleep-deprived a child is, the more nightmares they have. An overtired brain enters irregular sleep cycles, which provokes both nightmares and night terrors. So the first step with frequent nightmares is to sort out the routine: bedtime no later than 8:00 PM for a 3-year-old, 8:30 PM for a 4–5-year-old.
