A toddler suddenly afraid of the bath drain. A four-year-old who needs the door open and the landing light on. A baby who screams at every uncle who comes near. None of this is a sign anything is wrong; almost all of it follows a predictable timetable as cognitive development unlocks new ways of imagining the world. Knowing what is normal — and what to do about it — saves a great deal of unnecessary worry. Healthbooq (healthbooq.com) covers emotional development across the early years.
Fears Track With Brain Development
The fears children have at each age are not arbitrary. They map onto what the brain has just become able to imagine.
6 to 12 months: stranger anxiety and separation anxiety. The newly developed ability to recognise familiar faces means unfamiliar ones now register as different — and threatening. Object permanence is online, so an absent parent is a missing parent rather than a fact of the world.
18 months to 3 years: the fear repertoire expands as the child notices more of the world. Common: loud noises (hoovers, hand dryers, fireworks, motorbikes), animals — especially dogs and insects, the dark, water (the bath drain that "could suck them down"), toilets that flush noisily, large vehicles, men with deep voices, people in costumes (Father Christmas, mascots), being in the wrong arms by mistake.
3 to 5 years: as imagination becomes elaborate, fears do too. Monsters under the bed and in cupboards. Witches, ghosts, baddies from stories. The dark and what might be in it. Nightmares peak in this period.
5 to 8 years: more abstract. Fear of illness, fear of dying, fear of parents dying, fear of natural disasters, fear of getting in trouble. The cognitive ability to project into the future and imagine bad outcomes is now fully online.
8 to 12 years: social fears begin to dominate. Embarrassment, judgement, exclusion, being different. Existential worries about the world, climate, world events. Performance anxiety.
Each phase passes as the child accumulates experience and the next stage of cognitive development arrives.
What Doesn't Help
Two natural adult responses both make fears stickier:
Dismissal. "Don't be silly, there's nothing there." "Big boys aren't scared of the bath." Telling a child their fear is not real does not make it not real to them; it teaches them that the adults in their world will not help with it. They feel ashamed and stop bringing the fear out, but the fear continues.
Endless reassurance. Checking under the bed thirty times. Re-explaining at length why the hoover cannot eat them. Promising nothing bad will happen. Each reassurance feels helpful in the moment; the cumulative effect is to teach the child that there is, after all, something genuinely worth checking for. If reassurance truly worked, one round of it would be enough. The fact that the child needs more, every night, suggests it is not actually solving the problem.
A useful rule: answer once, kindly, with confidence. Then move on. "There are no monsters in your room. I'm here. Time for sleep." Don't get pulled into the negotiation.
What Does Help
Three things, consistently:
Acknowledge the feeling. "I can see this is feeling really scary for you. The drain is loud and big." Naming it lands; arguing with it doesn't. You do not have to agree the fear is realistic to acknowledge it is happening.
Stay calm. Children calibrate their fear by reading their parent's face. If your face says "this is not actually dangerous, but I see you're worried," the child learns that. If your face says "this is terrible and I don't know what to do," they learn that.
Gentle approach, not avoidance. This is the most counter-intuitive bit and the most evidence-based. Avoiding feared things produces relief in the moment and stronger fear over time. Approaching them — gradually, supported, at the child's pace — lets the brain learn the situation is survivable.
This does not mean forcing a screaming child to pet a dog. It means a graded ladder:
- Look at pictures of dogs together
- Watch dogs in a park from a bench, far away
- Get a bit closer
- Stand near a small calm friendly dog with the owner present
- Touch the dog briefly while it is calm
- Stay near a dog for longer
Spread across weeks. The child stays in each step until they are comfortable, then moves up. This is the same principle used in CBT for adult phobias and works for children too.
Specific Common Fears
The dark. A low-level night light is a reasonable accommodation. Not a brightly lit room. A small soft glow that lets the child see the room is what they remember it being. Torch games, reading bedtime stories with a torch, gradually dimming the light over weeks all help. Most children outgrow it.
Monsters. Engaging with the imaginative frame often works better than logic. "Monster spray" (water in a labelled bottle), a "brave box" of guardian objects, a stuffed dog that is "the night-time guard" — these are not deceptions. They give the child agency over the imagined fear, which is a transferable skill.
Loud noises. The hoover, hand dryers, fireworks, the toilet flush. Often eased by giving the child control where possible — letting the child press the button, getting them to do the flush themselves. For unavoidable big noises (fireworks): forewarn, headphones, a calm parent.
Strangers. Don't force greetings or hugs with relatives. The child's fear is normal and their right to bodily autonomy starts here. "She's getting used to you, give her a few minutes" is a kind way to say it. Many children warm up if not pushed.
Animals. Most realistic dog fears resolve with calm exposure to a calm dog. Keep dog-meeting low-pressure: child in your arms, dog being held by owner, calm voice, brief.
Bath drains, toilets. Common, almost always passes. A drain cover, a hand to hold, distraction. Don't force flushing in front of them; let them flush when ready.
Doctor's appointments, haircuts. Honest preparation in advance — what will happen, in what order, how long. A small reward planned for afterwards. Reading a book about it. The hardest cases benefit from a graded approach over multiple visits before the actual treatment.
Books That Help
Stories let children rehearse fear safely:
- Where the Wild Things Are — Maurice Sendak, monsters mastered through imagination
- The Bear Hunt — Michael Rosen, fearful adventure with safe ending
- Owl Babies — Martin Waddell, separation and reunion
- The Owl Who Was Afraid of the Dark — Jill Tomlinson, exactly what it says
- Llama Llama Misses Mama — Anna Dewdney, separation
- No Matter What — Debi Gliori, attachment and reassurance
- The Lion Inside — Rachel Bright, courage
Reading these regularly, in calm moments not just at bedtime, helps the narrative become a resource the child carries.
Nightmares vs Night Terrors
Worth distinguishing because the response is different.
Nightmares typically happen in the second half of the night. The child wakes, can be comforted, may remember the dream, often wants reassurance. Common in 3- to 6-year-olds. Comfort, reassurance, a brief return to bed; in the morning, talk briefly about it if the child wants.
Night terrors typically happen in the first third of the night. The child appears awake — sitting up, screaming, eyes open — but is not. They do not respond to comfort, do not remember it in the morning, and trying to wake them often makes it worse. Common between 3 and 8 years, peaking around 5 to 7. Stay nearby, keep them safe, do not try to wake them; it usually settles within ten to twenty minutes. Triggered by overtiredness, illness, fever, irregular sleep schedule. Reduce by improving sleep timing.
Neither requires medical input unless very frequent or causing injury.
When To Seek More Help
Most fears are temporary. The patterns that warrant a conversation with the GP or health visitor:
- The fear is preventing significant parts of normal life — not going to nursery, not sleeping in own room well past the typical age, refusing food categories, refusing the bath
- It is getting worse rather than easing over weeks
- The child has multiple fears layered together, suggesting general anxiety rather than a specific phobia
- The child has physical symptoms — stomach aches, headaches, sleep problems — connected to the fear
- The fear is interrupting the family or the child's quality of life consistently
Children's anxiety responds well to early support. CBT adapted for younger children, parental work (see the SPACE programme in the anxiety article), and sometimes school-based support all help. Many parents find a single conversation with the GP and some structured self-help reading enough — Cathy Creswell's Helping Your Child with Fears and Worries is the standard, evidence-based UK self-help book and is genuinely useful.
A Long View
The toddler scared of the bath drain becomes the four-year-old scared of monsters becomes the seven-year-old scared of getting things wrong at school. Each stage feels intense at the time and looks small in retrospect. Children whose adults take fears seriously without inflating them, who validate without arguing, and who help them gently approach rather than avoid, develop the skill of being afraid of things and doing them anyway. This is the most useful emotional skill there is, and it is built in the small daily moments of childhood fear.
Key Takeaways
Fears in young children are predictable, age-related, and almost always temporary. The mechanism that turns ordinary fears into lasting ones is avoidance. The most useful adult response acknowledges the fear, doesn't argue with it, and gently helps the child move toward the feared thing rather than away.
