Child afraid of the dark? How to help them feel brave at bedtime
Why nighttime fears show up, what the research says helps, the night light question, and when to get more support.
The short answer: Fear of the dark is a normal part of growing up. It often starts around age 2 to 3, when imagination takes off, and most children have nighttime fears at some point. What helps most is taking the fear seriously while showing calm confidence, practicing bravery in small steps, and keeping your child in their own bed with brief reassurance. If you use a night light, make it one, dim and warm.
Is it normal for a child to be afraid of the dark?
Yes. A pediatrician at Arnold Palmer Hospital for Children notes that fears of nighttime usually begin at about 2 to 3 years, when imagination "really kicks in" but children cannot yet tell fantasy from reality [1]. In a study of 176 children aged 4 to 12, 73% reported nighttime fears [2]. Their parents underestimated how often those fears happened [2], so it is worth asking your child directly.
| Age | What it often looks like |
|---|---|
| 2 to 3 | Monsters in the closet, the "bogeyman" in the corner, as imagination grows [1] |
| 4 to 6 | Common; telling real from pretend is still developing [2][3] |
| 7 to 9 | Even more frequent than at 4 to 6 [2] |
| 8 and up | Intruders and break-ins are the most common fear [4] |
Most children grow out of it. Researchers describe nighttime fears as transient for most children [5], and a psychologist at Children's Hospital Colorado says the phase can last from a few weeks to months [6]. Fears still show up in older kids: in a study of 511 young people aged 8 to 16, 79% of the children reported nighttime fears, compared with 49% of the teens [4].
Why is my child suddenly scared of the dark?
In the study of children aged 4 to 12, almost 80% linked their fear to scary information they had picked up (things they heard, read or watched), far more often than to a bad experience of their own [2]. Children's Hospital Colorado points to TV, online videos and even the news, to watching someone else be afraid, and to stressful times such as a move or a new school [6]. Arnold Palmer's pediatrician adds a new sibling, divorce or a death in the family [1].
If the fear appeared suddenly, look for what changed: a new show, a scary story from an older cousin, a big change at home.
What should I say when my child is scared of the dark?
Validate first, then show confidence. Children's Hospital Colorado suggests: "I know the dark feels scary sometimes, but I also know that you can do this" [6]. Cincinnati Children's says never to dismiss or make fun of a fear, because a fear that seems silly to an adult can feel very real to a child [7].
Scripts you can use:
- At lights out: "You're safe. We're right here, and we keep you safe all night." (Cincinnati Children's suggests reassurance like this [7].)
- When they call out: "I hear you. You're OK. I'll come check on you in five minutes."
- In the morning: "You stayed in your bed even though it felt scary. That was brave."
Two timing tips. Talk about the fear earlier in the day, when things are calm, rather than right before bed [6]. And skip threats like "the bogeyman will get you" [1].
How do I help my child feel brave in the dark?
Practice, in small steps, with praise. Reviews of the research found that behavioral and cognitive-behavioral approaches (gradual practice facing the fear, imagination games, brave self-talk and rewards) reduced children's nighttime fears, often within a few sessions [8][9].
Two simple tools have been tested with young children:
- A stuffed friend with a job. In a study of 104 children aged 4 to 6 with significant nighttime fears, children given a puppy doll to take care of had fewer fears after a month than a comparison group still on a waiting list, and the gains lasted six months. A version where the doll was presented as a protector worked just as well, and sleep problems improved too [10].
- A book you work through together. In a small study, 9 children aged 5 to 7 with persistent nighttime fears and a diagnosed phobia read Uncle Lightfoot, Flip That Switch with their parents over four weeks, doing its activities. Eight of the nine improved meaningfully and slept more nights in their own bed [5].
A brave ladder you can try at home (each step for a few days, moving on when your child is ready):
- Daytime dark games. Sit together in a dark closet or under a blanket for 30 seconds, then cheer [6].
- Flashlight hunt. Lights off in the bedroom in the afternoon; your child finds three toys with a flashlight.
- Their stuffed friend "keeps watch" or "needs looking after" at bedtime [10].
- Lights out with you in the doorway for one minute, then you leave.
- Spaced check-ins. Return briefly after 5 minutes, then 10, 15 and 20, until they fall asleep [7].
- Morning praise or a sticker for staying in bed.
Should my child sleep with a night light?
A night light is fine if it is dim and does not get in the way of falling asleep, says Cincinnati Children's [7]. Children's Hospital Colorado's psychologist adds a limit: not several night lights and not lights on all night, because kids need a dark room to sleep well. Stick with one dim night light, if anything [6].
The light research explains why "dim and warm" matters. In studies of preschoolers:
- An hour of bright light before bed lowered melatonin (a hormone that helps with sleep), and in most children it stayed low 50 minutes after the light went off [11].
- Even very dim light in that hour lowered melatonin [12] and moved the body clock later by about 56 minutes on average, about as much as bright light did [13].
- In a small, preliminary study, warm light (2700K) lowered melatonin less than cool white light (about 24% versus 56%), but it still shifted the clock [14].
In another small study of school-age children (average age 9), the same bright light lowered children's melatonin about twice as much as adults' [15]. One honest limit: these studies tested an hour of light before bed with children awake and looking at it, not a night light during sleep.
| If you use a night light | Why |
|---|---|
| Just one | Kids need a mostly dark room [6] |
| Dim | Even dim light acts on a young child's clock [12][13] |
| Warm (amber, not cool white) | Warm light had less effect than cool light [14] |
| Low and out of direct view | So it lights the floor, not your child's eyes |
Does monster spray work?
Experts differ on pretend fixes, so treat this as a judgment call. Cincinnati Children's advises against monster spray and "clear the room" rituals: they may suggest you believe in the monster too, and they can turn into a way to delay bedtime [7]. Arnold Palmer's pediatrician says not to "check under the bed one more time" [1].
On the other side, Children's Hospital Colorado's psychologist suggests using imagination as a tool, such as an "anti-monster" contract with rules (the monster may only visit on Thursdays and must stay quiet) [6]. And in the doll study above, a doll presented as a protector worked as well as one that needed care [10]. We could not find a study of monster spray itself.
Our view: pretend tools that put your child in charge seem reasonable, as long as they are short, done once and part of the routine, not a new reason to stay up.
What should I avoid?
- Moving your child into your bed or room. Cincinnati Children's suggests comforting them in their own room so they learn their bed is safe [7]. Colorado's psychologist says regular co-sleeping when afraid may make the fear worse over time [6].
- Lots of fear-focused rescue. In 109 preschoolers with nighttime fears, more parental fear-management behavior went with worse measured sleep [16]. This does not prove which came first.
- Scary shows, videos and books near bedtime [1][7].
- Staying until they fall asleep every night. Occasionally is OK, Cincinnati says, but not two nights in a row [7].

When to talk to your pediatrician
This guide is not medical advice. Talk to your child's doctor if:
- The fear continues despite your efforts, is severe, or shows up during the day too. Cincinnati Children's suggests an evaluation for anxiety at that point [7].
- It causes constant lost sleep or extreme anxiety at bedtime [6].
- It began around a big stressor, such as a move, divorce or a death in the family; a counselor may help [1].
- Your child has many fears beyond the dark. Preschoolers with severe nighttime fears often have more fears in general, and researchers see these fears as a possible early sign of anxiety [17]. In one study, nighttime fears were linked to an anxiety disorder in about 10% of children [2].
- Your child snores or breathes loudly or heavily in sleep, which is a different sleep problem [18].
Effective help exists. Behavioral and cognitive-behavioral treatments for nighttime fears have been tested in controlled studies with good results [9].
FAQ
At what age are kids afraid of the dark?
It often starts around age 2 to 3 [1], is common at 4 to 6 and even more frequent at 7 to 9 [2].
Will my child grow out of being scared of the dark?
Usually, yes. For most children nighttime fears pass with time [5], often within weeks to months [6].
Is a red or orange night light better?
Warmer light had less effect on melatonin than cool white light in one small study of young children, though it still shifted their body clocks [14]. We did not find a study of red night lights in young children.
Should I let my scared child sleep in my bed?
Hospital experts suggest comforting your child in their own room instead, and staying until they fall asleep only occasionally [6][7].
