Don't check the closet. Teach him to handle the dark.

Quick answer: Treat the fear as real and the monster as not real. Give your kid a job and a tool in the dark, stretch the time between your check-ins a little each night, and answer every 2 a.m. visit with the same short script. Boring beats clever.

It's 2 a.m. A small figure is standing beside your bed, breathing through his mouth, saying nothing. You know exactly what he wants.

What you do in the next ninety seconds, repeated for a couple of weeks, decides whether this fear fades or settles in. Most dads fail it one of two ways.

The two ways dads blow it

The brush-off. "There's nothing in there. Go to sleep." It's true, and it's useless. To a five-year-old, the dark isn't a fact problem. It's a feeling that shows up when the lights go out, and arguing with a feeling teaches him only that you don't get it. He'll stop telling you. He won't stop being scared.

The monster patrol. Flashlight sweep, closet door flung open, a dramatic "all clear." You mean well. But you've just confirmed that a search was warranted. Every night the search has to happen again, and it has to be better than last night's. You've hired yourself as a night security guard with no end date.

There's a middle road. You take the fear seriously and the monsters not at all. "That feels scary, I know. You're safe, and I'm right down the hall." Then you build his ability to handle it, one small step at a time.

Step one: win the dark in daylight

Don't start this at bedtime. Bedtime is when he's tired, you're tired, and nobody's thinking clearly.

On a Saturday, give him a flashlight that's his own. A cheap one with a button he can work himself is fine. Ownership matters. It turns him from a kid waiting to be rescued into a kid with equipment.

Then play in the dark on purpose, with the lights on in the rest of the house:

• Close the blinds in his room and let him find a stuffed animal you hid, using only the flashlight.
• Have him walk to the closet and back while you stand at the door.
• Let him pick the night-light himself. A warm, dim one is better than a bright blue one. Put it where it lights the floor, not his face.

Keep it light. Some of it should be a game, and a little bravado is fine. A kid who has done something in the dark on his own terms walks in at night with a different posture.

Step two: the check-in ladder

Here's where you hold the line. A plan only works if you run it every night, including the night you'd rather skip it.

After the usual routine (bath, teeth, a book, lights down), you tell him exactly what's going to happen:

"I'm going to leave, and I'll come back to check on you in two minutes. I'll always come back."

Then you leave and come back in two minutes. Not three. Not when you've finished the dishes. The whole thing runs on your word being good to the minute. Keep the visit short and dull: a hand on his shoulder, "Good job, you're doing it," out the door.

Each night, or every other night if he's struggling, stretch the gap. Two minutes, then four, then seven, then ten. By the time the gap gets long, he's usually asleep when you come back, which is the point.

Two cautions:

• If he's up out of bed, walk him back without a speech. Same words every time.
• Don't climb into his bed and stay until he's out. It feels kind. It teaches him he can't fall asleep without you there, and you'll be there until he's ten. Some families make the opposite call, and I'm not going to say they've wrecked their kids. But if the goal is a kid who can handle the dark on his own, this plan won't reach it.

Step three: the 2 a.m. script

He'll come to your bed at some point. Have the lines ready before it happens, because you won't have anything clever at that hour.

1. Stay calm and low. Your voice is the thermostat.
2. "I know it's scary. You're safe. Let's go back."
3. Walk him to bed. Tuck him in. Tell him you'll check on him in a few minutes, then actually do it.
4. No lecture, no negotiation, no snack, no TV.

The first few nights it will take twenty minutes and cost you a chunk of sleep. That's the price. If you're running on fumes, what to do with your kids when you've got nothing left is worth a read before the second week starts.

And if he gets loud about it, stay calm and keep to the script. You're not being cold. You're being the one steady thing in the house.

What to take off the table

A few things quietly feed the fear:

• Scary stuff in the daytime. Shows, games, even stories that seem mild to you. A kid's imagination has no off switch at night.
• Screens close to bed. Cut them well before lights-out. Screen rules that hold up when you're tired covers how to keep that rule alive past the second night.
• Bedtime negotiating. "One more glass of water" is stalling dressed as thirst. Water goes by his bed before the routine starts.
• Your own jokes about monsters. Skip them. The dark isn't funny to him yet.

When it's more than a phase

Fear of the dark is common, especially in the preschool and early school years, and most kids grow through it. But if the fear is intense, if it's spreading to other parts of his day, if it's wrecking his sleep for weeks or comes with other big changes in his mood or behavior, call his pediatrician. That's a conversation with a professional, not a failure on your part.

What he'll remember

He won't remember the flashlight game or the ladder. He'll remember that when he was afraid, his dad didn't mock it, didn't panic, and didn't leave him to it. He'll remember you came back every time, on the minute you said.

That's the long game. You're not building a kid who's never scared. You're building one who knows what to do when he is, and who already knows whose voice to listen for.
