Suddenly scared of the dark

The fear is the imagination arriving

This lands at two and three because that is when pretend play, magical thinking and the ability to picture what is not in the room all come online at once. The same equipment that produces a cardboard box becoming a boat produces a shadow becoming a thing with intent.

AAP notes that a more active imagination and a tendency toward magical thinking can make children afraid of things — and lists the toilet among them, which is worth knowing before you conclude your child's specific fear is unusually strange.

So the fear is not evidence of something scaring them. It is evidence of a new capability being tested on the nearest available material, which at 7pm is a dark room.

Most of this resolves on its own

AAP's framing is reassuring and worth quoting flat: occasional fears are common, most childhood fears are mild, and with reassurance and support they generally go away on their own after a while.

That matters because the pressure to fix it fast is what produces the two mistakes below. A fear that is going to fade in a few months does not need a strategy; it needs company while it fades.

Cope, not avoid

The principle underneath everything AAP recommends is that the goal is to COPE, not to avoid. A fear that is fully accommodated never gets disproved — the child learns the hall light is what kept the thing away, which makes the light load-bearing.

The method is small, non-threatening doses at their pace. AAP's worked example is a dog: talk about it, then look at photos or video, then watch a dog through a window, then eventually pet a puppy. Each step only when the last one is comfortable. That is desensitisation, and it works the same way on a dark room — sitting in it together with the light on, then dimmer, then the door open rather than the hall light on.

Praise the brave behavior when it happens, specifically. And talk about coping when they are CALM — not at 7pm mid-fear. AAP suggests practicing things like slow breathing, or picturing a safe place, at a time when nothing is frightening, so the tool exists before it is needed.

The two things not to do

Do not belittle or ridicule the fear, and particularly not in front of other children. AAP says this plainly. It is easy to do accidentally — 'there is nothing there, don't be silly' is a sentence most people have said — and it teaches a child that the fear is shameful, so the next one gets hidden rather than brought to you.

And do not pressure them into being brave. AAP again: it will take time for them to confront and gradually move beyond their anxieties. Forcing the pace turns one bad night into a fight about the bedroom itself.

On checking under the bed: it is fine, and it is not the cure. Checking WITH them, matter-of-factly, treats the fear as real and the room as safe. Elaborate rituals — monster spray, nightly sweeps — quietly confirm that monsters are the kind of thing one needs equipment for.

When it is more than a fear

AAP's line for a phobia is behavioral rather than emotional: a fear so extreme, persistent and focused that it significantly interferes with ordinary daily activities — refusing to play outside, refusing to go to nursery or school.

Interference is the test, not intensity. A child who is genuinely frightened at bedtime but plays, eats and goes out normally is inside the ordinary range, however loud the bedtime is.
