Why nightmares spike after a frightening event

A child's mind often keeps working through something scary at night, and that can show up as more frequent or vivid nightmares. This is a normal stress response, not a sign that something is wrong with your child. Because sleep and emotional well-being run in both directions, a stressful period can disrupt sleep, and disrupted sleep can make a child more emotionally raw the next day 1. Knowing this helps you respond with patience rather than alarm. For most children, the spike in nightmares is temporary and fades as the event becomes less raw and daily life feels predictable again.

What to do when your child wakes up scared

Go to your child calmly and let your presence do the reassuring. Keep your voice low and steady, and let them know they are safe and you are there. Avoid quizzing them about the dream in the middle of the night; comfort first, talk later if they want to. A brief, soothing routine, such as a hand on the back, a sip of water, and tucking them back in, helps them settle. Keeping the wake-up low-key and predictable teaches their body that nighttime is safe and that you will come, which over time reduces the fear around going back to sleep.

Daytime steps that make nights easier

Protect a calm, consistent bedtime routine and a regular sleep schedule, since steady routines are one of the strongest supports for healthy child sleep 2. Keep the hour before bed soothing, with no scary shows, news, or screens, and ideally no devices in the bedroom 2. School-aged children generally need 9 to 12 hours of sleep in 24 hours, and getting enough sleep supports better mood and emotional regulation, which makes hard feelings easier to handle 34. During the day, give your child small ways to feel in control: a nightlight, a favorite stuffed animal as a 'guard,' or a simple plan you make together for what to do if they wake up.

When a clinician helps

Reach out if nightmares stay frequent for more than a month, if your child is afraid to sleep, or if you notice daytime changes such as new fears, clinginess, irritability, or trouble at school after the frightening event. A pediatrician or child therapist can use a validated parent questionnaire like the Children's Sleep Habits Questionnaire to sort out what is driving the sleep problem and rule out other medical or behavioral causes 5. They can also coordinate with your child's school or daycare if the event is affecting them there. When sleep stays disrupted, evidence-based behavioral approaches help: cognitive-behavioral and sleep-focused strategies are first-line and improve children's sleep onset and quality 6. A clinician tailors these to your child's age and the specific event, and addresses any underlying anxiety so both sleep and daytime worry improve together.

What recovery usually looks like

Most young children gradually have fewer and milder nightmares over a few weeks as the scary event loses its grip and routines feel safe again. Progress is rarely a straight line; a stressful day or a reminder of the event can bring a temporary uptick. Keep responding the same calm way, protect sleep, and give it time. Steady, predictable comfort is what helps a child's nervous system relearn that nighttime is safe.

Common questions

Should I wake my child during a nightmare?

Generally no. If they are already awake and scared, comfort them calmly. If they seem to be dreaming but not fully awake, you can gently soothe them back to sleep rather than fully waking them.

Is it okay to let my child sleep in my bed after a nightmare?

An occasional night is fine for comfort, but try to return your child to their own bed when possible so they relearn that their room is safe. Consistency at bedtime helps most over time.

How long is too long for nightmares to last?

Occasional nightmares are normal. If they stay frequent for more than about a month, or your child is afraid to sleep or seems changed during the day, it is worth checking in with a clinician.
