It's three in the morning, and your child is standing by the bed in tears again. Or it takes two hours to fall asleep, even though everyone is worn out. Sleep problems in children are among the most common worries parents have, and at the same time among the most underestimated. Because when children don't sleep well, the whole family suffers: the days get harder, nerves fray, and sooner or later you start wondering whether something serious is going on.
The good news: most childhood sleep problems are temporary, and with the right knowledge and a little patience they can be brought under control. This article gives you an overview of typical sleep problems by age, explains the difference between harmless phases and disorders that need treatment, and shows concrete ways to help your child, and you, sleep restfully again.
Typical sleep problems by age
Children's sleep is constantly changing. What's normal at six months can point to a problem at four years, and vice versa. That's why it's worth looking at the different stages of development.
Infants and toddlers (0–3 years)
In the first months of life, babies don't yet have a fixed day-night rhythm. Waking often is biologically sensible and no cause for concern. Between six and twelve months, many children start to sleep through the night, though by no means all of them. Separation anxiety, teething, and developmental leaps can throw sleep off again and again during this phase.
In the toddler years, new challenges often show up: the child doesn't want to go to bed, climbs out of the crib, demands endless rituals, or wakes at night and wants to come into the parents' bed. All of this is part of normal development, but it can be exhausting.
Preschoolers (3–6 years)
At this age, nightmares and nighttime fears become more common. Children develop a vivid imagination, and suddenly there are monsters lurking under the bed. At the same time, they process the day's impressions in their sleep, which can lead to restless nights. The shift away from the afternoon nap toward staying awake all day also often brings a spell of poorer nighttime sleep.
School-age children (6–12 years)
School-age children usually sleep more steadily, but new pressures like performance expectations, social conflicts, or an overloaded schedule can disrupt sleep. Screen time in the evening plays an increasingly big role at this age. The blue light from tablets and smartphones suppresses melatonin production and pushes the natural time of falling asleep later.
Nightmares and night terrors: two different phenomena
Parents often confuse nightmares with what's known as night terrors (pavor nocturnus), yet these are fundamentally different phenomena.
Nightmares happen in the second half of the night during REM sleep. The child wakes up, can describe the dream, and needs comfort and closeness. Occasional nightmares are completely normal, especially during periods of big change.
Night terrors usually occur in the first two to three hours after falling asleep. The child screams, thrashes around, has their eyes open, but isn't really awake. The next morning, they remember nothing. As frightening as it looks to parents, night terrors are harmless and usually go away on their own.
With night terrors, the rule is: don't wake the child, just wait it out and make sure they don't hurt themselves. With nightmares, on the other hand, your child needs your presence and the reassurance that they're safe.
The power of an evening routine
A reliable evening routine is the single most effective way to protect good sleep in children. Children need predictability in order to feel safe and let go. A good routine doesn't have to be complicated, but it should happen in a similar form every evening.
The same sequence: dinner, then brushing teeth, putting on pajamas, reading a story, lights out. The order gives the child a sense of orientation and signals to the body: now it's time to sleep.
Calm transitions: at least 30 minutes before bedtime, things should settle down. No roughhousing, no screens, no exciting stories. Instead: quiet conversations, soft music, or cuddling together.
Set times: the body gets used to regular bedtimes. Variations of more than 30 minutes, even on the weekend, can throw the rhythm off.
The bed as a safe place: a child's bed should be used only for sleeping. Playing, eating, or watching TV in bed blurs the association between bed and sleep.
Co-sleeping: yes or no?
Few topics are debated as passionately among parents as sharing a bed as a family. The research is nuanced: from a developmental-psychology standpoint, there's nothing wrong with co-sleeping, as long as the safety rules are followed, no pillows or blankets near the baby, and no alcohol or medication affecting the parents.
Many families find that co-sleeping makes nights calmer, because the child settles more quickly and the parents don't have to get up every time. Others find that their own sleep suffers, or that the switch to a separate bed becomes difficult.
There's no single solution that works equally well for every family. What matters is this: if everyone involved sleeps well, the sleep arrangement is fine, whether that's in the family bed or in a room of their own.
Screen time and sleep quality
Tablets, smartphones, and televisions are now a fixed part of everyday family life. For children's sleep, though, they have a noticeable effect. Studies show that children who use screens in the evening fall asleep 20 to 30 minutes later on average and sleep more restlessly overall.
There are several reasons for this: the blue light suppresses the body's own release of melatonin, the content stimulates the brain, and the constant stimulation makes it hard to wind down. As a rule of thumb, pediatricians recommend: no more screens for at least an hour before bedtime. For children under two, screen time before sleep is generally discouraged.
One practical approach: set up a charging station in the hallway or the kitchen where all the devices find their place in the evening. That way there's no power struggle over the phone, just a clear family rule that applies to everyone, adults included.
When fear keeps a child from falling asleep
Some children don't have a sleep disorder in the medical sense, they're simply afraid of being alone in the dark. These fears are part of development and are especially common between the ages of three and eight. Monsters under the bed, burglars, or the vague worry that something might happen to their parents, thoughts like these can turn falling asleep into an ordeal.
Take these fears seriously without amplifying them. Lines like "there's nothing there" don't help much, because they dismiss what the child is feeling. Better: work out a fear plan together. Some families have had good results with a "worry-eater" (a stuffed animal that "eats up" the fears), a dreamcatcher over the bed, or a short relaxation ritual with breathing exercises. A night light or an open door can also give the child the sense of safety they need.
When you should see a professional
Occasional sleep problems are normal in children and no reason for a medical work-up. You should pay closer attention if:
your child regularly takes more than 30 minutes to fall asleep over a period of several weeks
they wake often during the night and can't settle themselves
there's noticeable daytime tiredness, trouble concentrating, or changes in behavior
your child snores, has pauses in breathing during sleep, or sleeps with their mouth open
they show unusual movements in their sleep, such as rhythmic head-banging or teeth-grinding
the lack of sleep is pushing you as a family to your limits
The first person to turn to is your pediatrician. They can rule out physical causes, such as enlarged tonsils behind snoring or a thyroid problem. For more complex issues, they'll refer you to a sleep clinic or to child therapists who specialize in sleep problems.
Concrete help for everyday life
Keep a sleep log: for two weeks, note down when your child falls asleep, when they wake, and anything notable. Patterns often emerge that get lost in the stress of daily life.
Movement during the day: children who get enough activity during the day fall asleep more easily in the evening. At least an hour of exercise outdoors works wonders.
Watch food and drink: a heavy dinner or sugary snacks before bed can disrupt sleep. A light dinner one to two hours before bedtime is ideal.
Optimize the sleep environment: dark, cool (16–18 degrees), and quiet. A small night light is fine, but it should be warm white light, not blue light.
Stay patient: improvements in sleep take time. Expect at least two to three weeks of consistent effort before a new routine settles in.
Good sleep as a family project
Children's sleep problems are rarely a sign that parents are doing something wrong. They're part of development and, in the vast majority of cases, very treatable. What children need is a safe place to sleep, reliable routines, and parents who stay calm despite their own exhaustion, even if that's easier said than done.
If you feel the situation is becoming too much, don't hesitate to look for help. Sleep counseling can bring noticeable improvements within just a few sessions. And sometimes simply knowing that you're not alone with these nights is enough to get through the next sleepless one a little better.
