How to Help a Child Who Can’t Sleep: What the Research Says

A child who cannot sleep is one of
the most exhausting and most worrying
parenting experiences — exhausting
because sleep deprivation affects
the whole family, and worrying because
a child who consistently cannot sleep
is a child whose development, health,
and wellbeing are being compromised
every night. Research on pediatric
sleep provides specific, evidence-based
guidance about what genuinely helps —
and what makes sleep difficulties worse.

This article covers what the research
shows about helping a child who cannot
sleep — the most common causes, the
most effective approaches, and what
parents can specifically do.

Understanding Why Your Child
Cannot Sleep

Research on pediatric sleep difficulties
finds that identifying the specific
cause of a child’s sleep difficulty
is the essential first step — because
different causes require different approaches.

The most common causes of
difficulty falling asleep:

Anxiety. Research consistently
finds anxiety the most common
cause of sleep onset difficulty
in children. The quiet of bedtime
removes the distractions that
manage anxiety during the day —
leaving worry to dominate at
the moment the child most needs
to be mentally quiet.

Signs that anxiety is driving
sleep difficulty:
Repeated requests for reassurance at bedtime.
Specific worries expressed at bedtime.
Difficulty being alone at night.
Nightmares with anxious content.

Screen use before bed. Research
on screens and sleep consistently
finds that screen use in the
evening — particularly engaging
content — delays sleep onset
through blue light suppression
of melatonin and psychological
arousal that prevents mental wind-down.

Inconsistent bedtime and routine.
Research on circadian rhythm
and sleep finds that inconsistent
bedtimes — varying by more
than thirty to sixty minutes —
significantly disrupt the body’s
natural sleep-wake cycle, making
falling asleep at any consistent
time more difficult.

Overstimulation before bed.
Research on pre-sleep arousal
and sleep onset finds that
exciting or stimulating activity
close to bedtime — active play,
exciting content, stimulating
conversation — produces physiological
and psychological arousal that
significantly delays sleep onset.

Caffeine. Research finds that
caffeine — in sodas, energy
drinks, chocolate, and tea —
significantly delays sleep onset
in children. Research finds
that caffeine consumed as early
as six hours before bed can
affect sleep onset.

Environmental factors. Research
on sleep environment finds
that noise, light, temperature,
and bedroom comfort significantly
affect sleep onset. Research
supports a cool, dark, quiet
sleep environment.

What the Research Shows Works

The consistent calming bedtime
routine — the foundation of
everything. Research on bedtime
routines and pediatric sleep
consistently finds that a consistent,
calming bedtime routine — the
same sequence of activities
each night — is the single
most effective sleep intervention
for most children.

Research-supported bedtime routine:
Begin winding down thirty
to sixty minutes before the
target sleep time.
Consistent sequence — bath
or shower, pajamas, teeth,
reading, lights out.
Calm, low-stimulation activities only.
Screens off at least one hour before the routine begins.
Warm, connected ending —
reading together, brief conversation,
expression of love.
Consistent end point — lights
out at the same time each night.

For anxiety-driven sleep difficulty.
Research on anxiety and sleep
identifies several specific approaches:

Worry time earlier in the
evening. Research on worry
containment and sleep finds
that designating a specific
brief worry time — at least
one hour before bed — containing
worry to a specific time and
preventing it from dominating the bedroom.

Breathing exercises at bedtime.
Research on breathing and sleep
onset finds that slow deliberate
breathing — particularly extended
exhalation — activates the
parasympathetic nervous system
and significantly supports sleep onset.

A worry journal. Research
on expressive writing and anxiety
finds that writing down worries —
and then closing the journal —
significantly reduces bedtime
anxiety in school-age children.

Gradual approach to sleeping alone.
Research on separation anxiety
and sleep finds that gradually
reducing parental presence
at bedtime — over one to two
weeks — produces better outcomes
than either indefinite co-sleeping
or abrupt separation.

A comfort object. Research
on transitional objects and
child sleep finds that a specific
comfort object — a stuffed
animal, a special blanket —
significantly supports sleep
onset by providing felt security
in the parent’s absence.

Cognitive approaches for older
children. Research on cognitive
behavioral therapy for pediatric
insomnia finds that helping
older children challenge catastrophic
thoughts about sleep — “I’ll
never get to sleep,” “something
terrible will happen” — significantly
improves sleep onset.

For screen-related sleep difficulty.
Research supports:
Screens off at least one hour before bed — strictly and consistently.
Devices charging outside the bedroom overnight.
Replacing screen time before
bed with calming alternatives —
reading, gentle music, quiet conversation.

For inconsistent routine-related difficulty.
Research supports:
Choosing a specific bedtime
appropriate for the child’s age — and holding it consistently.
Consistent bedtime including weekends —
varying by no more than thirty minutes.
The same sequence every night —
consistency is more important
than the specific activities chosen.

For overstimulation-related difficulty.
Research supports:
Beginning the wind-down period
thirty to sixty minutes before the target sleep time.
Transitioning to calm, low-stimulation
activities — reading, gentle
music, quiet conversation.
Avoiding exciting play, screen
content, or stimulating conversation close to bedtime.

Relaxation techniques for children.
Research on relaxation and
pediatric sleep identifies several
effective techniques:

Progressive muscle relaxation —
tensing and releasing muscle
groups systematically — produces
physical relaxation that supports sleep onset.

Guided imagery — imagining
a calm, safe, pleasant place —
distracts from anxiety and
produces relaxation.

Body scan — gently focusing
attention on each body part
from feet to head — produces
relaxation and focuses attention
away from anxious thoughts.

Slow breathing — four counts
in, six counts out — activates
the parasympathetic nervous
system and supports sleep onset.

What Does Not Help

Staying with the child until
they fall asleep — long term.
Research on parental presence
and sleep finds that while
parental presence helps in
the short term — long-term
dependence on parental presence
for sleep onset prevents the
development of independent
sleep skills and produces ongoing sleep difficulties.

Inconsistent responses. Research
on behavioral consistency and
sleep finds that inconsistent
responses — sometimes staying,
sometimes not, sometimes allowing
the child into the parental
bed — maintain sleep difficulties
by preventing the consistent
learning that sleep skill development requires.

Screens as a sleep aid. Research
on screens and sleep consistently
finds that using screens —
even calm content — as a sleep
aid delays rather than supports
sleep onset.

Try This This Week

Practice 1 — The Bedtime Routine Establishment
What it is: A deliberate establishment
of a specific consistent calming
bedtime routine — the most evidence-based
sleep intervention available.

How to do it: This week establish
a specific routine:

Choose a specific bedtime.
Create a written sequence —
bath, pajamas, teeth, reading, lights out.
Begin thirty to sixty minutes
before target sleep time.
Screens off one hour before
the routine begins.
Hold it consistently every
night this week — including weekends.

Why it works: Research on
bedtime routines and sleep consistently
finds that consistent calming
routines — held every night —
significantly improve sleep
onset time and sleep quality
in children of all ages.

Practice 2 — The Breathing Practice
What it is: A brief daily practice
of slow breathing at bedtime —
building the relaxation tool
that sleep onset requires.

How to do it: Each night at
bedtime this week — practice
slow breathing together:

In through the nose for four counts.
Hold for two counts.
Out through the mouth for six counts.
Repeat five times.

Make it a warm, calm part
of the bedtime routine.

Why it works: Research on
breathing and sleep onset consistently
finds that slow deliberate breathing —
particularly extended exhalation —
activates the parasympathetic
nervous system and significantly
supports sleep onset by reducing
physiological and psychological arousal.

Practice 3 — The Worry Time Practice
What it is: A brief designated
worry time earlier in the evening —
containing anxiety before it
reaches the bedroom.

How to do it: For children
whose sleep difficulty appears
anxiety-driven — establish a
brief worry time at least one
hour before bed:

“Let’s have our worry time now —
what’s on your mind?”
Child shares worries briefly.
Acknowledge and problem-solve where possible.
“Worries are done for tonight —
we’ll think about anything
else tomorrow.”

Why it works: Research on
worry containment and sleep
consistently finds that designating
a specific worry time earlier
in the evening — and actively
closing worries before the
bedroom — significantly reduces
anxiety-driven sleep onset difficulty.

The Bottom Line

A child who cannot sleep needs
specific, targeted support —
matched to the specific cause
of their sleep difficulty. The
research is clear: a consistent
calming bedtime routine is
the foundation; screens out
of bedrooms and off before
bed is essential; anxiety-driven
sleep difficulty requires specific
anxiety management approaches;
and relaxation techniques practiced
in calm conditions are significantly
more effective than those introduced
for the first time at bedtime.

The child who has a consistent
warm bedtime routine, a screen-free
bedroom, specific relaxation
tools, and a parent who responds
with calm consistency — develops
the sleep skills that adequate
sleep requires.
